Answer:
Oxygen is more electronegative than sulphur
Explanation:
Bond angle of a molecule is related to the electronegativity of the central atom. The more electronegative the central atom is, the greater the bond angle.
As electronegativity of the central atom increases, the magnitude of bond pair- bond pair repulsion increases leading to increase in bond angle.
Hence, oxygen, being more electronegative than sulphur asserts a greater bond pair- bond pair repulsion leading to a greater bond angle in water.
Answer:
its pb because it has large number of electrons

Answer:
<u>The pressure inside becomes : 202.646 KPa</u>
Explanation:
Given ,
- <em>The temperature inside the cylinder is constant</em>
- <em>The number of moles of the gas inside the cylinder will also be constant because it's a closed one.</em>
<em>Now according Boyle's law , </em>
- <em>The pressure of a gas of fixed mass is inversely proportional to its volume at a constant temperature.</em>
Thus ,
![P_1V_1=P_2V_2\\](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2%5C%5C)
is the initial pressure ![7.257*102*10^3 Pa](https://tex.z-dn.net/?f=7.257%2A102%2A10%5E3%20Pa)
is what we need to find
- initial volume
- final volume
∴
![7.527*102*10^3*12.49=P_2*47.32\\P_2=2.02646*10^5Pa](https://tex.z-dn.net/?f=7.527%2A102%2A10%5E3%2A12.49%3DP_2%2A47.32%5C%5CP_2%3D2.02646%2A10%5E5Pa)
The pressure inside becomes : 202.646 KPa
During the night. It usually forms after midnightish
If the concentration of enzyme increases, then reaction should speed up (answer C).
enzyme speeds up a chemical reaction by lowering activation energy to provide an alternative pathway of reaction mechanism. assuming that enzyme which usually is the limiting factor, the increase of enzyme concentration should lead to more product formation i.e. maltose from the breakdown of starch.
the enzyme discussed here should be amylase.
higher temperature beyond optimum value enzyme found in our human body will usually least to denaturation of active site of enzyme. hence lead to loss of enzyme activity permanently.
