5. If the reaction of carbon monoxide and oxygen gas in question 2
zheka24 [161]

Answer: The mass in grams is 514.8.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given molecules}}{\text{Avogadros number}}

given molecules = 7.03\times 10^{24}  

Putting in the values we get:

\text{Number of moles}=\frac{7.03\times 10^{24}}{6.023\times 10^{23}}=11.7moles

mass of CO_2=moles\times {\text {Molar mass}}=11.7mol\times 44g/mol=514.8g

The mass in grams is 514.8.

It is thought that __________ caused past ice age climates.
Mkey [24]

It is thought that Milankovitch cycles caused past ice age climates.

This cycle is related to the movement of earth

The cycle has three parts eccentricity, axial tilt, and precession. These three are supposed to be deciding factor for the amount of heat reaching on earth from sun

thus the complete Milankovitch cycle do affect the temperature and hence the climate on earth.
