Answer:
The final temperature of the water is 28.98 degree Celsius.
Explanation:
It is given that,
Mass of sample of water, m = 52 grams
Initial temperature,
Heat absorbed,
The specific heat of water is
We need to find the final temperature of the water. The heat absorbed is given by the formula as follows :
So, the final temperature of the water is 28.98 degree Celsius.
Electronegativity is a measure of the ability of an atom to attract electrons. The value tends to increase on moving from left to right across a period in the periodic table. This is because as the atomic number increases so does the nuclear charge which causes the added electron to experience a stronger nuclear attraction.
For example, if the consider the second period, then Lithium which is present in the extreme left will show a greater tendency to lose electrons (lower electronegativity) while Fluorine present in the extreme right will show a greater tendency to attract electrons and therefore high electronegativity. Thus, when Li and F combine, they form what is called an ionic bond.
Ans C) True statement
It should be a 3 because there are 6 oxygens and to balance the equation you need to balance the reactants side so you put a 3 so the products are the same as the reactants
Answer:
D.)more collisions --> greater collision force --> higher pressure
Explanation:
The temperature of an ideal gas is directly proportional to the average kinetic energy of the particles in the gas, according to the equation:
where
KE is the kinetic energy
k is the Boltzmann's constant
T is the absolute temperature of the gas
As a result, when the temperature of a gas increases, the kinetic energy of the particles increases too. This means that overall, they will move faster, therefore there will be more collisions between the particles and the walls of the container. As a result, the particles will exert on average a greater force of collision agains the walls, and therefore, they will exert a higher pressure.
So, the correct option is
D.)more collisions --> greater collision force --> higher pressure
