Specific heat is the heat capacity of an object divided by its mass in grams.

Chemistry

True. This is because specific heat depends on the heat capacity and the unit of mass. Mass, as we know is measured by grams, so this is a correct statement. 

Answer: True
shutvik [7]3 years ago

True, because molar heat capacity is the amount of heat required to raise 1 mol of a compound by 1 Kelvin. 1 mol of a compound has an equal number of grams to his molar molecular mass. Therefore, dividing it by the mass of 1 mol (aka molecular mass) is equal to amount of heat required to raise 1 gram of the substance by 1 degree Kelvin.

<u>Chemistry</u>

<u>Stoichiometry</u>

  • Using Dimensional Analysis
<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] 2Al₂O₃ → 4Al + 3O₂

[Given] 20 mol Al₂O₃

<u>Step 2: Identify Conversions</u>

[RxN] 2 mol Al₂O₃ → 4 mol Al

<u>Step 3: Stoich</u>

  1. [DA] Set up:                                                                                                     \displaystyle 20 \ mol \ Al_2O_3(\frac{4 \ mol \ Al}{2 \ mol \ Al_2O_3})
  2. [DA] Multiply/Divide [Cancel out units]:                                                         \displaystyle 40 \ mol \ Al

<u>Step 4:Check</u>

<em>Follow sig fig rules and round. We are given 1 sig fig.</em>

Since our final answer already has 1 sig fig, there is no need to round.

If an atom has 35 protons in nucleus how many neutrons will it have orbiting the nueclues
Dvinal [7]

Answer

Because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. So, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.

The Earth's mantle is
EleoNora [17]

Answer:

C. cooler than both the crust and the core

Explanation:

It is observed that at the mantle, temperatures range from estimatedly 200 °C (392 °F) around the upper boundary with the crust to approximately 4,000 °C (7,230 °F) at the core-mantle boundary.

So we can say the mantle is cooler than both the crust and the core.
