How many mg of salt are in a 2.78 kg bag of salt?

Answers

Answer 1

Answer:

2,780,000mg

Explanation:

Using the Metric Staircase photo provided, you can calculate how many mg there are in 2.78 kg by simply moving the decimal point six places to the right, since the "Kilo" step takes six places to move to the "Milli" step.

2.78 kg

---------------

2 7 8 0 0 0 0 .

we can see that the decimal point is moved to the right six places.

compare the temperature and thermal energy of hot soup in a small mug and that of hot soup in a large bowl

Answers

Explanation:

Both have the same temperature, but the large bowl of soup has more thermal energy than the small mug because there is more matter present in the bowl.

The temperature of both the bowl is same , but the thermal energy of large bowl is more than the thermal energy of small bowl.

What is thermal energy?

Thermal energy is defined as the energy of an object or system due to the movement of its molecules and atoms. It is produced with rise in temperature.  

It is also defined as internal energy present in a system in the state of thermodynamic equilibrium by virtue of its temperature.

Thermal energy is also known as heat energy.

Thermal energy is directly proportional to mass of the object.
Thermal energy sources include natural gas, coal, and oil, as well as solar, heat pump electric, and geothermal heat.

Thus, the temperature of both the bowl is same , but the thermal energy of large bowl is more than the thermal energy of small bowl.

Answers

The enthalpy change for reaction (2) is 10178 kJ/mol.

What is enthalpy of reaction?

The term enthalpy of reaction has to do with the heat that is evolved or absobed in a chemical reaction.

We have the equations;

C8H18(l) + 12.5O2(g) -----> 8CO2(g) + 9H2O(g).16CO2(g) + 18H2O(g) ----->2C8H18(l) + 25O2(g)

We can see that equation (2) is obtained from (1) by multiplication using a factor of 2. and also (2) is a reverse of (1). It then follows that the enthalpy change for reaction (2) is 10178 kJ/mol.

6. Model conservation of mass in a labeled drawing that illustrates a physical change.

Answers

Answer:

hope it's help you

Explanation:

In an isolated system, neither chemical processes nor physical changes can create or destroy mass, according to the principle of mass conservation. According to the law of conservation of mass, the mass of the products and reactants of a chemical reaction must be equal.

Why is mass conservation crucial?According to the law of conservation of mass, matter cannot be created or destroyed in a chemical reaction. When wood burns, for example, the mass of the soot, ashes, and gases equals the original mass of the charcoal and oxygen when it first reacted. As a result, the product's mass equals the reactant's mass. The understanding that substances do not, contrary to appearances, vanish as a result of a reaction, but rather change into another material of equal mass, was made possible by the law of conservation of mass, which was essential to the development of chemistry. The law of conservation of mass does not always apply.

what's going to be in the he World​

Answers

Answer:

Lots of people set the alarm with the best of intentions, knowing that's the time they need to get up to meet the day's demands. But then the alarm clock seems to ring way before they're ready to rise, so they're hitting snooze and, eventually, running late. Something's got to give.

The key lies inside your body. "An important factor in being able to wake up easily at the desired time in the morning is the timing of one's circadian rhythm, or 'body clock,'" says sleep researcher Leon C. Lack, PhD, professor emeritus in the school of psychology at Flinders University in Adelaide, Australia. Much of what you need to do to wake up on time starts by planning your sleep schedule the day and the evening before — and by making your mornings count.

How do our internal clocks work, and how much can we control them? According to the National Institutes of General Medical Sciences (NIGMS), the body’s master clock, located in the brain, produces and regulates our circadian rhythms, which help determine sleep patterns over the course of a 24 hour period. Environmental signals, such as daylight and darkness, affect circadian rhythms, too. When incoming light hits the optic nerves, information is passed along from the eyes to the brain. When there is little or no light — at night — your clock tells the brain to make more melatonin, a hormone which makes you sleepy.

Our sleep-wake cycles, hormone levels, metabolism, and body temperature are all affected by our circadian rhythms, notes the National Institute of Neurological Disorders and Stroke. When your rhythm is off, you may be at risk for more than just a few groggy days you drag yourself through. Irregular rhythms, the NIGMS notes, have been linked to chronic health conditions, such as obesity, diabetes, depression, bipolar disorder, and seasonal affective disorder.

But there are ways to recalibrate your system to get the sleep you need and wake up feeling refreshed and ready for the day ahead. Physiological and psychological factors come into play, and it’s not always easy to get a good night’s rest or adhere to a schedule so that you consistently go to sleep and get up around the same time each day.

Why do you have to have a certain number of reactants on one side?

Answers

Answer:Because you need that certain number and double the number of bread to get the reactants off of the sides

Explanation: 4 bread reactants- 2meat reactants- 2 cheese reactants= 2 products

The reason for the presence of a certain number of reactants on one side is to ensure that the chemical equation is balanced.

In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of that element on the product side.

Consider the equation:

[tex]2H_2 + O_2 - > 2H_2O.[/tex]

This equation represents the reaction of hydrogen gas ([tex]H_2[/tex]) with oxygen gas ([tex]O_2[/tex]) to form water ([tex]H_2O[/tex]).

To balance this equation, double the coefficient in front of [tex]H_2O[/tex] on the product side, resulting in 4 hydrogen atoms and 2 oxygen atoms on both sides.

Therefore, having a certain number of reactants on one side is necessary to ensure that a chemical equation is balanced, satisfying the law of conservation of mass.

how many sodium atoms are present in 0.2310 g of sodium?

Answers

Answer:

There are 6.048X10^21 atoms present in 0.2310 g of sodium.

Explanation:

We know,

23g Na contains 6.022X10^23 atoms

∴1g Na contains 6.022X10^23/23 atoms

So, 0.2310g Na contains (6.022X10^23/23)X0.2310 atoms

                                         = 6.048X10^21 atoms

There are 6.048X10^21 atoms present in 0.2310 g of sodium.

The number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.

The given parameters;

mass of the reacting sodium = 0.231 g1 mole of an atom = 6.02 x 10²³ atomsthe atomic mass of sodium is 23 g/mol

The number of moles of 0.231 g of sodium available is calculated as;

[tex]no. \ of \ moles = \frac{Reacting \ mass}{Molar \ mass} \\\\no. \ of \ moles = \frac{0.231}{23} \\\\no. \ of \ moles = 0.01 \ mol.[/tex]

The number of atoms of 0.01 mole of sodium available is calculated as;

1 mole ---------- 6.02 x 10²³ atoms

0.01 ----------------- ?

= 0.01 x 6.02 x 10²³ atoms

= 6.02 x 10²¹ atoms.

Thus, the number of atoms present in 0.231 g of sodium is 6.02 x 10²¹ atoms.
