Answer:
See below
Explanation:
<u>Specific Heat of water</u> = 4.186 J/(g-C)
J/(g-C) multiplied by g and C results in J
4.186 * 540 * (95-32) = <u>142 407 .72 J</u>
The element used to make the first atomic bomb is uranium
Answer:
A. 3.2L of NO
B. 4.8L of H2O
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
4NH3 + 5O2 —> 4NO + 6H2O
A. Determination of the litres of NO produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 4L of NO.
Therefore, 4L of O2 will produce = (4x4)/5 = 3.2L of NO.
B. Determination of the litres of H2O produced from the reaction. This is illustrated below:
From the balanced equation above,
5L of O2 produced 6L of H2O.
Therefore, 4L of O2 will produce = (4x6)/5 = 4.8L of H2O
Answer:
(c) Polyatomic
Explanation:
For a mono atomic gas, the specific heat at constant pressure is 5R/2. For a diatomic gas, the specific heat at constant pressure is 7R/2.
Since 11R/2 is larger than both 5R/2 and 7R/2 it cannot be mono atomic or diatomic hence the gas is polyatomic.
R is the gas constant.
I think the correct answer from the choices listed above is the second option. A way that the elements are grouped on the periodic table would be that elements with similar bonding properties are in the same column. <span>Each column is called a </span>group<span>. The elements in each </span>group<span> have the same number of electrons in the outer orbital.</span>
