Answer:
True
Explanation:
The arrangement of three groups COOH, CO, OH in the order of reducing boiling point is as follow -
COOH > OH > CO
COOH gets strongly polarised due to the presence of electron withdrawing carboxy group and hence have strong H+ bonds as compared to that of alcohol.
Hence the given statement is true.
Answer:
5 mL
Explanation:
When an object is completely submerged in a liquid , it displaces liquid equal to its volume . Therefore level of liquid is raised in a container containing liquid .
When the irregularly shaped object is totally submerged the volume of water in a graduated cylinder increases from 10 mL to 15 mL.
Initially volume of water contained = 10 mL
volume of water + volume of irregular shaped object = 15 mL
volume of irregular shaped object = 15 - 10 = 5 mL .
<span>The water cycle describes the existence and movement of water on, in, and above the Earth. Earth's water is always in movement and is always changing states, from liquid to vapor to ice and back again.</span>
The radiosity of this surface is 299.95W/m².
<h3>
Calculation :</h3>
Given, € 0.8
Ta=0°C 273K
For opaque body., T = 0
a+ p = 1
€ = a (Kirchoff's Law)
p = (1-E)
Radiosity = leaving energy from the surface
= px 240 +€σT4
= (1-E) × 240 +0.8 x 5.67 x 10-8 (2734)
= (1-0.8) × 240 +0.8 x 5.67 × 10-8 (2734)
= 299.95W/m²
So, now after doing the calculations we can say that the radiosity of the surface was 299.95W/m².

Answer:
Option B. 10
Explanation:
If 1 mol of butanol contains 6×10²⁴ atoms of H, let's calculate the amount of H.
(number of atoms / NA)
6.02 x 10²³ atoms ___ 1 mol
6×10²⁴ atoms will occupy (6×10²⁴ / NA) = 9.96 moles
H, has 10 moles in the butano formula.
