Answer:
Double Bonds
Explanation:
CO2 has two double bonds going from carbon to the oxygen atoms. Each oxygen atom needs to bond twice and the carbon atom needs to bond four times. Carbon has four valence electrons, and oxygen has six. Carbon shares two of its valence electrons with each of the two oxygen atoms, forming two double bonds.
Answer:
This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs. Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood.
Explanation:
Its IUPAC name is sodium carbonate. It is also known as soda ash. It is the water soluble sodium salt of carbonic acid and occurs as a crystalline heptahydrate. Sodium carbonate has an alkaline taste and when in solution forms a basic solution. One important application is that it is used commonly as a water softener.
Answer:
Granite
Explanation:
The specific heat capacity of a substance, which is denoted by "c", is the amount of heat required to raise the temperature of a particular mass of that substance by 1°C. It is calculated as follows:
c = Q ÷ m∆T
Where;
c = specific heat capacity
Q = amount of heat (J)
m = mass of substance
∆T = change in temperature.
According to this equation and explanation above, a low specific heat capacity means that the rate at which the temperature is raised is slow and vice versa. Hence, from this question, GRANITE with specific capacity of 0.790 J/gK will raise temperature the slowest.
