Answer:

Distance in kilometre = 4.242 x 10¹² km

Explanation:

Given:

Distance of Proxima  Centauri = 4.242 light years

Find:

Distance in kilometre

Computation:

1 light year = 10,000,000,000,000 km

So,

4.242 light years = 4.242 x 10,000,000,000,000

Distance in kilometre = 4.242 x 10¹² km

Answer:

True

Explanation:

Sometimes you will need to convert from grams to moles, or moles to grams

The balanced equation

BaCl₂(aq)+ K₂CO₃(aq)--> BaCO₃(s) + 2KCl(aq)

Given

word equation

Required

Balanced equation

Solution

Convert to chemical equation :

Reaction

BaCl₂(aq)+ K₂CO₃(aq)--> BaCO₃(s) + KCl(aq)

aBaCl₂(aq)+ K₂CO₃(aq)--> bBaCO₃(s) + cKCl(aq)

K, left = 2, right = c⇒c=2

C, left = 1, right = b⇒b=1

Ba, left = a, right = b⇒a=b⇒a=1

The equation becomes :

BaCl₂(aq)+ K₂CO₃(aq)--> BaCO₃(s) + 2KCl(aq)

you will need to be sure to count all of atoms on each side of the chemical equation. Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Aluminum + Iron (II) oxide

Answer:

4.5 M Na+

Explanation:

Multiply the molarity by the volume of the solution to get moles.

Note that there are TWO sodium ions in sodium carbonate, therefore the first-mole calculation must be multiplied by two.

Since molarity is defined as moles of ions/liters of solution, the final molarity will be the sum of the calculated moles divided by the sum of the liters of solution.

Hope this helps :)

Answer:

Look at the properties of Oxygen and Silicon - the two most abundant elements in the Earth's crust - by clicking on their symbols on the Periodic Table.

Explanation:

Answer:

D. silicon and oxygen

Explanation:

The most abundant elements on the earth's crust are silicon and oxygen. Silicon and oxygen forms a wide range of silicate minerals they are found in the crust.

There are many silicates which are derived from the basal units of silicon and oxygen combining together. Other atoms or elements then combines with the silicate framework.

Oxygen is about 46% abundant in the crust whereas silicon takes about 28% to be the second most abundant element on the crust.

Silicate minerals abounds in rocks and within the soil.

2 i think i am not very good at this lol

Explanation:

The units that acceleration use are distance/time^2  (in metric units).

The acceleration is the change of velocity over time, so

In another way, if the velocity is constant, the acceleration is zero, but if the velocity change over the time (as a car do when the red light change), the acceleration takes value!.

ionic bonds form between metals which form positively charged ions and nonmetals which form negatively charged ions.

Answer: An atom with 6 protons, 5 electrons, and 7 neutrons

Explanation: In this case, neutrons do not matter as they have a charge of 0, or no charge. A proton has a charge of +1 and an electron has a charge of -1. Since there are 6 protons, the total charge of the protons would be +6. Since there are 5 electrons the total charge of the electrons would be -5. +6 - 5 would result in a charge of +1. This means that this atom would have an overall charge of + 1. Basically, if there is one more proton than electron, then the overall charge of the atom will be +1 but if there is one more electron than proton, then the overall charge of the atom will be -1.

Explanation:

Answer:

Explanation: The longer the alkyl chain, the less soluble in water is the alcohol. Methanol and ethanol are infinitely miscible in water; propanol and butanol have limited solubility. ... Hydrogen bonding with water thus becomes less viable, and solubility of the long-chain alcohol IN WATER decreases.

Answer:

7.5 moles of hydrogen is required

Explanation:

Given data:

Number of moles of H₂ needed = ?

Number of moles of NH₃ = 5 mol

Solution:

Chemical equation:

N₂ + 3H₂     →     2NH₃

Now we will compare the moles of ammonia and hydrogen.

         NH₃       :         H₂  

          2           :          3

          5           :         3/2×5 = 7.5 mol

Thus, 7.5 moles of hydrogen is required.

The percent by mass of Tin : = 27.08%

Given

25.00 g of the compound

6.77 g of Tin

18.23 g of Bromine

Required

The percent by mass of Tin

Solution

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison, so that compounds have a fixed composition of elements

%mass X = (mass X/mass sample) x 100%

So %mass of Tin :

= (6.77 g : 25 g) x 100%

= 27.08%
