The three factors can affect gas pressure are temperature, its volume, and the number of its particles.
What is the gas pressure?
The force exerted by gaseous molecules as they collide with the walls of their container is referred to as gas pressure. If the volume and temperature of a gas container remain constant, increasing the number of gas particles causes an increase in pressure, and vice versa.
Automobiles have tires. These tires (or tyres in British English) must have air pressure. Inflatable beds and baloons are two additional examples.
The pressure rises as the number of gas particles in a container increases. The pressure increases as the volume of a container increases.
Thus, The enclosed gas's pressure is determined by the number of gas particles, the volume of the container, and the temperature of the gas.

The number of moles in 987 grams of Ra(OH)2 = 3.8 moles
Calculating number of moles
Ra = 226g
O= 16g
H = 1
Therefore molar mass of Ra(OH)2= 226+ (16+1)×2
= 260g/mol
The molar mass of Ra(OH)2 = 260g/mol
Thus means that 260g of Ra(OH)2 makes up 1 mole
Therefore, 987 g = X moles
Make X moles the subject of formula,
X mole = 987/260
= 3.8 moles
Therefore, the number of moles in 987 grams of Ra(OH)2 = 3.8 moles

Answer : 3.79 moles are in 987 grams of .
Solution : Given,
Mass of = 987 g
Molar mass of = 260 g/mole
Now we have to calculate the moles of .
Formula used :
Now put all the given values in this formula, we get the moles.
Therefore, 3.79 moles are in 987 grams of .
Which type of reaction is represented?
(1) single replacement (3) synthesis
(2) double replacement (4) decomposition
Answers
Answer: (1) single replacement
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus magnesium can easily lose electrons as compared to silver and result in the formation of magnesium nitrate and silver.
Double displacement is a chemical reaction in which ion exchange takes place.
Synthesis reaction is a chemical reaction in which two reactants combine to give a single product.
Decomposition is a chemical reaction in which one substance decompose to give two or more than two products.
Which type of reaction is represented?
double replacement
double replacement a bimolecular process involving the exchange of bonds between the two reacting chemical species, which
results in the creation of products with
similar or identical bonding affiliations.
To illustrate, consider two chemical species, AB and CD, which react to give AD and CB:
AB + CD → AD + CB
