How does increased air temperatures affect salinity of the oceans and the great
ocean conveyor belt?

1. increased air temperatures decreases the salinity of the ocean since more ice is
melting adding more freshwater to the oceans, therefore slowing down the great
ocean conveyor belt.

2. increased air temperatures decreases the salinity of the ocean since more ice is
melting adding more freshwater to the oceans, therefore speeding up the great ocean
conveyor belt.

3. increased air temperatures increases the salinity of the ocean since more water is
evaporating into the atmosphere, therefore slowing down the great ocean conveyor
belt.

4. increased air temperatures increases the salinity of the ocean since more water is
evaporating into the atmosphere, therefore speeding up the great ocean conveyor
belt.

Answers

Answer 1

Increased air temperatures decrease the salinity of the ocean since more ice is melting adding more fresh water to the oceans, therefore slowing down the great ocean conveyor belt.

What is an ocean conveyor belt?

Ocean conveyor belt system in which water moves between the cold depths and warm surface in oceans throughout the world.

Increases in temperatures of surrounding entities like ice and an increase in precipitation adds fresh water into the sea, which lower salinity. Seawater with lower salinity is lighter in density and won't sink as much as denser water.

As the seawater gets saltier, its density increases, and it starts to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.

Hence, option A is correct.

¿Qué provoca la acidificación de los océanos?

Cuando el CO2 es absorbido por el océano, se producen reacciones químicas. En particular, se forma ácido carbónico y se liberan iones de hidrógeno; como resultado, el pH de las aguas superficiales del océano disminuye, haciéndolas más ácidas.

The empirical formula of a chemical substance is CH₂. The
molar mass of a molecule of the substance is 56.108 g/mol.
What is the molecular formula of the chemical substance?

Answers

Answer:

Explanation:

Remark

CH2 provides the basic structure of the hydrocarbon. It will be multiplied by some factor determined by the number of grams / mol. I will use rounded numbers because all periodic tables are slightly different.

Theoretical mass of CH2

1 C = 1 * 12 = 12

2 H= 2 * 1 =  2

Mass CH2 = 14

The multiplier for CH2

56.108 rounded = 56

Multiplier = molar mass (rounded)/Mass CH2

Multiplier = 56/14 = 4

Chemical

(CH2)_4 = C4H8

Answer: C4H8

ladybug beetles chase, capture, and eat smaller insects called aphids. which best describes this relationship?

Answers

The relationship is predation. The ladybugs are the predators and the aphids are the prey.

What is predation?

Predation is an interaction in which one organism, the predator, eats all or part of the body of another organism, the prey.

As per the information in the question, Ladybug beetles chase, capture, and eat smaller insects called aphids.This means that aphids act as food sources for Ladybug beetles.

Predation can be described as a biological interaction between two organisms belonging to two different species where one organism ( called predator) captures and consumes/eats another organism ( that is called prey).

Answers

The position of equilibrium lies far to the right, with products being favoured. Hence, option A is correct.

What is equilibrium?

Chemical equilibrium is a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.

A very high value of K indicates that at equilibrium most of the reactants are converted into products.

The equilibrium constant K is the ratio of the concentrations of products to the concentrations of reactants raised to appropriate stoichiometric coefficients.

When the value of the equilibrium constant is very high, the concentration of products is much higher than the concentration of reactants.

This means that most of the reactants are converted into products and the position of equilibrium lies far to the right, with products being favoured.

Hence, option A is correct.

Answers

The molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol, Option D is the correct answer.

What is enthalpy of Combustion ?

The energy released when a fuel is oxidized by an oxidizing agent is called enthalpy of Combustion.

It is given that

a 1.0 g sample of magnesium is burned to form MgO. in doing so, 25.5 kj of energy are released.

Molecular weight of Magnesium = 24.35g

24.35 g makes 1 mole of Mg

1g = 1/24.35

For 0.04 moles  25.5 kJ is released

for 1 mole 25.5 *1/.04

how many grams of water would require 22000 joules of heat to raise its temperature from 34 C to 100 C. THe specific heat of water is 4.2 j/g C

Answers

The mass of water required to raise 22000 joules of heat from a temperature of 34°C to 100°C is 79.37g.

How to calculate mass?

The mass of a substance can be calculated by using the following formula:

Q = m × c × ∆T

Where;

Q = quantity of heat absorbed or releasedm = mass of substancec = specific heat capacity∆T = change in temperature

22000 = m × 4.2 × (100 - 34)

22000 = 277.2m

m = 22000/277.2

m = 79.37g
