Which describes an effect that ocean currents have on short-term climate change? Ocean currents increase the strength of prevail
zalisa [80]

The movement of the ocean and sea waves in a direction is called the ocean currents. Ocean currents can bring cold water, which cools the land and atmosphere.

<h3>What are the effects of ocean currents?</h3>

Ocean currents are the movement of the oceanic waves by the influence of the gravitational forces that can affect the atmosphere and the climate of the region.

Oceanic currents are capable of carrying cold water from polar areas to the regions of the equator resulting in a cooling atmosphere over the geosphere.

Therefore, option B. oceanic currents carry colder air to the warmer regions.

1. What happens when you add buttermilk (an acid) to baking soda (a base) in a mixing bowl does the pH increases or decreases or
Brums [2.3K]

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

Consider the fructose-1,6-bisphosphatase reaction. Calculate the free energy change if the ratio of the concentrations of the pr
Lyrx [107]

Answer:

The free energy change for the reaction at 37.0°C is -8.741 kJ.

Explanation:

The free energy of the reaction is given by :

\Delta G=\Delta G^o+RT\ln K

where,

\Delta G^o = standard Gibbs free energy

R = Gas constant = 8.314J/K mol

T = temperature in Kelvins

K = equilibrium constant

We have :

\Delta G^o=-16.7 kJ/mol=-16,700 J/mol

1 kJ = 1000 J

T = 37.0 C = 37 +273.15 K = 310.15 K

Ratio of concentrations of the products to the concentrations of the reactants =K = 21.9

\Delta G=-16,700 J/mol+8.314J/K mol\times 310.15 K \ln[21.9]

=-8,741.22 J = -8.741 kJ

The free energy change for the reaction at 37.0°C is -8.741 kJ.
