Answer:

Explanation:

1)This reaction is an acid base reaction. Baking soda is made up of sodium bicarbonate has it's PH above 7,while the Buttermilk contains some fatty acids with it's PH below 7, neutralization would occur when mixed together, and the pH of the mixture must be close to 7 which is neutral pH.

2) PH of 7(Neutral PH)

3)Self-raising flour has baking powder as one of its constituents. It also cotains cream of tartar, bicarbonate soda as well as calcium aluminium phosphate, the carbon dioxide from Bicarbonate of soda is released when reaction with acid takes place, then the Cream of tartar turns to tartaric acid when it is mosturized , then the reaction between them will produce bubbles of carbon dioxide in the cake, causing the cake to rise.

4)It makes a good household cleaner because it react with organic chemicals such as oil or grease then break them down like without attacking the metals that is attached to them.Bases contain particles called hydroxide ions. The higher the amount of hydroxide ions present in a base , the stronger it is.

5) The harsh acid or bike in the stomach creates a burning sensation in the back of your throat which irritate the food pipe line. Ifthe acid reflux is severe, it's reffered to as gastroesophageal reflux

A 0.89% (w/v) sodium chloride solution is referred to as physiological saline solution because it has the sameconcentration of s
elixir [45]

Answer: Molarity of a physiological saline solution is 0.15 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

n = moles of solute

V_s =volume of solution in ml

Given : 0.89 g of sodium chloride in 100 ml of solution.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{0.89g}{58.5g/mol}=0.015moles

Volume of solution = 100 ml

Molarity=\frac{0.015\times 1000}{100ml}=0.15M

Molarity of physiological saline solution is 0.15 M

Write a paragraph, citing examples from the text, to explain how Dr.
grigory [225]

Paul J. Chirik developed methods associated with chemistry catalysis and transition metals, which may result useful for the development of manufacturing technologies.

<h3>What is catalysis?</h3>

Catalysis refers to the chemical processes that increase the rate of different types of reactions by lowering its activation energy.

Proteins (enzymes) are biological catalysts that increase the rate of chemical reactions in biological systems.

Catalysis may be reached by using transition metals (e.g., actinium and rutherfordium), which result useful in the development of manufacturing technologies.

What is an advantage of using natural gas rather than a coal burning power plant?
Olenka [21]

Answer:

I hope it helps u

Explanation:

The advantages of using natural gas rather than coal are the following,

  • Natural gas is present in large amount than coal.
  • Natural gas is less costly than other fossil fuel sources of energy.
  • It increases security by decreasing dependence.
  • Natural gas is more environmentally friendly.
  • Natural gas is much safer to store.
  • It is reliable.
  • Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil.
  • Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant.

Is kp or kc larger (both at 300 k) for the reaction 2 nh3(g) ⇀↽ n2(g) + 3 h2(g) ? 1. they are both the same. 2. kc is larger. 3.
fgiga [73]
The equation is 2 NH3 (g) ⇀↽ N2 (g) + 3 H2 (g) 
Difference in the number of moles delta n = ((3 + 1) - 2) = 4 - 2 = 2 
We have an equation Kp= Kc (R x T) ^ (delta n); R is constant and T = 300 K 
Kp / Kc = (R x T) ^2 Based on the temperature value (300 K), we can conclude that Kp is Larger.
