Compare and contrast the conditions required for snow and rain to form.

Answers

Answer:

Snow forms when the atmospheric temperature is at or below freezing, and there is a minimum amount of moisture in the air. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain

Explanation:

When water vapor cools and condenses forms clouds, that is, return to water or rain.

When the temperature in the atmosphere is at or below freezing 0 degrees Celsius and there is a minimal amount of moisture in the air, snow forms.

How does rain form?

Clouds are formed by evaporating water or ice from the Earth's surface, or by plants releasing water and oxygen as a result of photosynthesis.

Water evaporates, or rises from the Earth's surface into the atmosphere, creating a gas called water vapor.

When water vapor cools and condenses—that is, returns to liquid water or ice—it forms clouds.

How does snow form?

A significant snowstorm or blizzard requires three factors:

Cold air (below freezing).Clouds and precipitation require moisture to form.Clouds and snow form when moist air rises over very cold air.

Thus, these are the conditions for snow and rain.

During an investigation, a scientist burned 48 g of magnesium strip. After the reaction, the total mass of the product formed was found to be 80 g. Does the law of conservation of mass hold true in this case? Use complete sentences to justify your answer based on numerical calculations.

Answers

Answer

yes

Explanation:

the law of conservation of mass hold true in this case burning magnesium strip is explained by this equation 2 Mg (s) + O2 (g) -> MgO (s)So the lighter magnesium, after reacting with oxygen in air, forms the heavier magnesium oxide. molar mass of magnesium and magnesium oxide are 24g and 40g respectively. So the same ratio 24:40 (i.e. 3:5) is maintained in the given masses of 48g and 80g, which means mass is conserved in the reacion.

The diagram which shows the repeating groups of atoms that make up the ending substances is C.

What are repeating group?

Repeating group is defined as a group of fields or attributes that show up repeatedly in a database table. It is a widespread issue that affects both big and small businesses, and it can have a variety of effects. An attribute that appears more than once in each row of a table is known as a repeating group. A relational table cannot contain "repeating groups," as they are a feature of pre-relational systems.

On most metals, a reaction could be seen when acids were applied. A gas and heat were created when the metal vanished. The new chemicals' chemical characteristics are distinct from those of the original substances.

Thus, the diagram which shows the repeating groups of atoms that make up the ending substances is C.

Suppose a snack bar is burned in a calorimeter and heats 2,000 g water by 20 °C. How much heat energy was released? (Hint: Use the specific heat equation.) Give your answer in both joules and calorie

Answers

Answer:

Explanation:

Remember that the key is the water so

using the formula q=m*s*deltT

We have the mass 2000g

we have the specific heat of water which is 1.00 cal/ g C

and the final temperature 20 C

Remember that delt T is the change in temperature meaning (Tfinal - Tinitial) Assuming that the water is at room  temperature (25 C)  before starting the reaction then

q= (2000 g)(1.00 cal/g C)(20-25)

q= -10, 000 cal  

if you want you can convert to joules by multiplying by 4.314 J

In more simpler terms - If all the heat released was absorbed by the water, and it takes 1 calorie of heat to raise

the temperature of 1 gram of water by 1°C that is a total of 20 times 2000 or 40,000 cal.

or 40 kilocalories. If you want it in joules, there are 4.184 joules to one calorie so it is

4.184 times 40 or 167.36 kilojoules.

Hope that helped

A snack that, when burned, heats 2,000 g of water by 20 °C, releases 4.0 × 10⁴ cal (1.7 × 10⁵ J).

A snack bar is burned in a calorimeter and heats 2,000 g  (m) of water by 20 °C (ΔT).

We can calculate the heat absorbed by the water (Qw) using the following expression.

[tex]Qw = c \times m \times \Delta T = \frac{1cal}{g.\° C } \times 2,000 g \times 20 \° C = 4.0 \times 10^{4} cal[/tex]

where,

c: specific heat capacity of water

According to the law of conservation of energy, the sum of the heat absorbed by the water (Qw) and the heat released by the combustion (Qc) is zero.

[tex]Qw + Qc = 0\\\\Qc = -Qw = -4.0 \times 10^{4} cal[/tex]

Finally, we can convert -4.0 × 10⁴ cal to J using the conversion factor 1 cal = 4.18 J.

[tex]-4.0 \times 10^{4} cal \times \frac{4.18 J}{1cal} = 1.7 \times 10^{5} J[/tex]

A snack that, when burned, heats 2,000 g of water by 20 °C, releases 4.0 × 10⁴ cal (1.7 × 10⁵ J).

this is the question and i dont know which reasoning i should use for the claim "If you follow the instructions, the POW kits will always heat the water above the correct temperature for pasteurization (65°C), but some people didn’t follow the instructions."

Answers

Answer:

I think this evidence supports this claim because Evidence Card b says “One man got sick, but his two children did not. He used water from Whip River. He used  the cube to heat the first pitcher of water, which he gave to his kids, and then reused the  cube without reheating for the second pitcher, which he drank himself.”

Explanation:

The correct reasoning for the given claim is shown by evidence 2.

What is water pasteurization?

Pasteurization is a method of disinfecting water without boiling it using heat or radiation.

Evidence 2 is the correct reasoning to explain the fact that if we follow the instructions the kit will always heat the water above the correct temperature for pasteurization (65°C). Second evidence is that “One man got sick, but his two children did not. He used water from Whip River. He used  the cube to heat the first pitcher of water, which he gave to his kids, and then reused the  cube without reheating for the second pitcher, which he drank himself.”

Hence evidence 2 is the correct reasoning.
