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

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.

What is the hybridization of the central atom in CO2? Hybridization = What are the approximate bond angles in this substance? Bo

const2013 [10]

Answer:

Explanation:

Hybridization is the combination of atomic orbitals to yield equivalent hybrid orbitals of appropriate energy which can participate in bonding.

In every compound there is a central atom. The central atom is usually the least electronegative atom in the molecule. In this case the least electronegative atom in the molecule is carbon.

The bond between carbon and oxygen in CO2 is intermittent between a pure double and a pure triple bond. Hence, carbon is sp hybridized.

The process by which DNA becomes mRNA occurs where within the cell?

creativ13 [48]

Answer: Transcription

In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.

Charcoal is primarily carbon. what mass of co2 is produced if you burn enough carbon (in the form of charcoal) to produce 4.80 k

Reika [66]

When carbon is burned in air carbon iv oxide gas is formed.
C (s) + O2 (g) = CO2(g) ΔH = - 393.5 kj/mol
The enthalpy change of the reaction is -393.5 j/mol which means that when one mole of carbon is completely burnt in air then 393.5 j of energy is evolved.
Thus, 1 mole = -393.5 j , then for 480 kj
= 480 × 1/393.5
= 1.2198 moles
1 mole of carbon iv oxide is equal to 44 g
thus, 1.2198 moles will be 1.2198 × 44 = 53.6712 g of CO2
