Which units express specific heat capacity?J/°C, J/K, cal/°C cal/K J
/(gi°C), J/(giK), cal/(gi°C), cal/(giK)
J, cal
°C, K

Answers

Answer 1

Answer:

Answer : The correct option is $(J)/(g^oC),(J)/(gK),(cal)/(g^oC),(cal)/(gK)$ .

Explanation :

Specific heat capacity : It is defined as the amount of heat required to raise the temperature of one gram of substance by one degree Celsius.

Formula used :

$q=mc\Delta T\nc=(q)/(m\Delta T)$

where,

q = heat required

m = Mass

c = specific heat capacity

$\Delta T$ = change in temperature

The unit of heat are expressed in terms of Joules, calories.

The unit of temperature are expressed in terms of degree Celsius, kelvin.

It is expressed as $(J)/(g^oC),(J)/(gK),(cal)/(g^oC),(cal)/(gK)$ .

Answer 2

Answer:

The units to express specific heat capacity are cal/K, cal/ $\rm ^\circ C$ , J/K, and J/ $\rm ^\circ C$ . Thus the correct option is A.

Specific heat can be defined as the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree celsius.

The expression for specific heat has been,

heat = mass $*$ specific heat capacity $*$ change in temperature

Calorie or Joule = g $*$ specific heat $*$ K or $\rm ^\circ C$

Specific heat will be:

cal/k
cal/ $\rm ^\circ C$
J/ $\rm ^\circ C$
J/K

Thus, the units to express specific heat capacity are cal/K, cal/ $\rm ^\circ C$ , J/K, and J/ $\rm ^\circ C$ . Thus the correct option is A.

Give one example each of an aqueous solution of a strong base and an aqueous solution of a weak base

Answers

An example of an aqueous solution of a strong base is NaOH (sodium hydroxide) in water. The NaOH dissociates completely in water into Na+ and OH- ions. An example of an aqueous solution of a weak base is NH3 (ammonia) in water. Here, the NH3 does not completely dissociate because it is a weak base.

Which energy transformation occurs when anelectrolytic cell is in operation?
(1) chemical energy → electrical energy
(2) electrical energy → chemical energy
(3) light energy → heat energy
(4) light energy → chemical energy

Answers

The correct answer is option 1. The operation in an electrolytic cell transforms energy from chemical energy to electrical energy. This is a cell which electrolysis occurs to produce electrochemical reaction and eventually producing an electric current.

How many total atoms are in 3(SO)4

Answers

Answer:

17 atoms are in 3(SO)4

Explanation:

Final answer:

There are 15 total atoms in $3(SO)4.$

Explanation:

To find the total number of atoms in a chemical formula like 3(SO)4, you need to multiply the subscripts (the numbers outside the parentheses) by the number of atoms represented by each element within the parentheses and then multiply that by the coefficient (the number outside the formula).

In this case, you have:

$3(SO)4.$

Now, let's break it down:

The subscript for sulfur (S) is 1.

The subscript for oxygen (O) is 4.

So, for each (SO4) unit, you have 1 sulfur atom and 4 oxygen atoms.

Now, multiply this by the coefficient of 3:

$3(SO)4.$ = 3 * (1 sulfur atom + 4 oxygen atoms)

= 3 sulfur atoms + 12 oxygen atoms

So, in $3(SO)4.$ , there are a total of 3 sulfur atoms and 12 oxygen atoms, for a combined total of 15 atoms.

Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) 2NH3(g) What occurs when the concentration of H2(g) is increased?

Answers

Given the equation representing a reaction at equilibrium: N2(g) + 3H2(g) = 2NH3(g). When the concentration of the hydrogen gas is increased, the equilibrium will tend to go to the products or to the forward reaction. Therefore, more products are formed.
