Answer

Vr = 0.5mol / s

Explanation

To calculate the reaction rate we have to divide the amount of substance consumed and the time it was consumed.

Vr = mol / t = 1.5moles / 3s

Vr = 0.5mol / s

The rate of reaction is 0.050 mol·s⁻¹.

For the reaction

P_4 + 5O_2 \longrightarrow P_4O_{10}\\

\text{rate} = \frac{\Delta P_4O_{10} }{\Delta t } = \frac{\text{1.5 mol }}{\text{ 30 s }} = \text{0.050 mol}\cdot \text{s}^{-1}\\

A 2.40 kg block of ice is heated with 5820 J of heat. The specific heat of water is 4.18 J•g^-1•C^-1. By how much will it’s temp
MrMuchimi

Answer: The temperature rise is 0.53^0C

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q=m\times c\times \Delta T

Q = Heat absorbed by ice = 5280 J

m = mass of ice = 2.40 kg = 2400 g   (1kg=1000g)

c = heat capacity of water = 4.18J/g^0C

Initial temperature  = T_i

Final temperature = T_f  

Change in temperature ,\Delta T=T_f-T_i=?

Putting in the values, we get:

5280J=2400g\times 4.18J/g^0C\times \Delta T

\Delta T=0.53^0C

Thus the temperature rise is 0.53^0C

What is true about all real machines?
AfilCa [17]

Answer:It is always greater than the actual mechanical advantage because all machines must overcome friction. The mechanical advantage of a machine may be greater than, less than, or equal to 1, depending on the type of machine.

Q # 4 in a polar covalent bond
Makovka662 [10]

Answer : The correct option is, electrons are not shared equally between atoms.

Explanation :

Polar covalent bond : It is a type of chemical bond in which a pair of electrons are not shared equally between the two atoms.

In polar covalent bond, the electrons are not shared equally because one atom spends more time with the electrons than the another atom. In this, one atom has more tendency to pull an electron than the other atom.

For example : H_2O is an example of polar covalent bond. In water molecule, oxygen spends more time with the electron than the hydrogen and oxygen carries a partial negative charge.
