Bicyle tyres become flat when the weather is clod. Explain​

Chemistry
1 answer:
Andreas93 [3]3 years ago
6 0

Answer:

Explained below

Explanation:

When cold weather is approaching, a lot of motorists usually experience a warning light that indicates low-pressure on the dash board or they simply notice that the tires now look a little less full than they should have prior to that time.

The primary reason for that low pressure indication is the drop in temperatures, which now causes the air to get denser and in return, consequently lower the tire pressure.

In essence the tires will lose air pressure because they contract in the cold season.

An individual suffering from a high cholesterol level in her blood. if the total blood volume of the individual is 5.2 l, how ma
Usimov [2.4K]

If the concentration of cholesterol is 238mg/100ml:

238 mg ==> 100ml

2380 mg (or 2.38g) ==> 1000ml (1L)

So the concentration will be 2.38 g/L of cholesterol.

if the volume is 5.2 L, the total grams of cholesterol would be :

m = C . V = 2.38g/L * 5.2 L = 12.376 grams of cholesterol.

HBrO(aq) + H2O(l) ⇄ H3O+(aq) + BrO−(aq)   Keq=2.8×10−9
Verdich [7]

Answer: The equilibrium concentration of BrO^- will be much smaller than the equilibrium concentration of HBrO, because Keq<<1

Explanation:

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as K_{eq}

K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.

For the given chemical reaction:

HBrO(aq)+H_2O(l)\rightarrow H_3O^+(aq)+BrO^-(aq)

The expression for K_{eq} is written as:

K=\frac{[H_3O^+]\times [BrO^-]}{[HBrO]}

Concentration of pure solids and liquids is taken as 1.

K=2.8\times 10^{-9}

Thus as K_{eq} , That means the concentration of products is less as the reaction does not proceed much towards the forward direction.

Answer:

1 mole of water (H2O)

Explanation:

Water has a chemical formula of H2O, there will be 2 moles of hydrogen in every mole of water.

In one mole of water, there will exist approximately 6.02×10^23 water molecules.

So, there will be a total of 6.02×10^23×2≈1.2⋅10^24 hydrogen atoms.
