Answer:

I'm thinking its "Your friend had colder winters than you do."

Explanation:

It is not "Your friend has warmer winters than you do." Or "You Have less precipitation than your friend does." I was doing this quiz before that had this question and its not those.

In the ocean side the the winter will be colder by the ocean breeze in the day time. The location of your friend farther from the ocean will have  warmer winters than you.

Any wind that flows from a big body of water onto or onto a landmass is called a sea breeze or an onshore breeze. Sea breezes form as a result of changes in air pressure brought on by the different heat capacities of water and dry land. Sea breezes are therefore more confined than prevailing winds.

A sea breeze is frequently seen along coasts after sunrise because land warms up far more quickly than water does when exposed to solar radiation. While dry ground also cools faster than water, a land breeze or offshore breeze has the opposite effect.

In winter seasons, along with the sea breeze make the climate more colder than that in locations farther from oceans. Hence, option b is correct.

Answer:

0.13 grams of O2

Explanation:

Just did worksheet

Answer: 1. 2 moles of oxygen atoms = 32 grams

2. 2 moles of oxygen molecules = 64 grams

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number of particles.

1 mole of oxygen atom (O) weighs = 16 g

Thus 2 moles of oxygen atom (O) weighs = [tex]\frac{16}{1}\times 2=32 g[/tex]

Also 1 mole of oxygen molecule [tex](O_2)[/tex] weigh = 32 g

Thus 2 moles of oxygen molecule [tex](O_2)[/tex] = [tex]\frac{32}{1}\times 2=64 g[/tex]

Answer:

False

Explanation:

The nucleus controls the cells activities

Answer: 1.80 moles of [tex]H_2[/tex] will be produced 1.20 moles of aluminium.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

The balanced chemical reaction is:

[tex]6HCl(aq)+2Al(s)\rightarrow 3H_2(g)+2AlCl_3(aq)[/tex]  

According to stoichiometry :

2 moles of [tex]Al[/tex] produce = 3 moles of [tex]H_2[/tex]

Thus 1.20 moles of [tex]Al[/tex] will produce=[tex]\frac{3}{2}\times 1.20=1.80moles[/tex]  of [tex]H_2[/tex]

Thus 1.80 moles of [tex]H_2[/tex] will be produced 1.20 moles of aluminium.

because the sun is at the center of the universe the planet orbit the sun its basically a simple answer so if you need more help im right here

The sun and the planets are part of the solar system. The sun is in the center of the system, and the planets revolve around it. Thus, option C is correct.

A solar system is a part of the Milky Way galaxy that includes the planets, stars, sun, moon, asteroids, etc. The Sun is the star that is fixed at the center of the system.

The planets are not fixed and revolve in orbit around the sun and rotate on their axis. The sun and planets are made up of gases and have different atmospheres.

Therefore, option C. sun is at the center around which the planets revolve.

Explanation:

The chemical formula for barium hydroxide is Ba(OH)₂

This means one mole of barium hydroxide contains one mole of barium, two moles of hydrogen, and two moles of oxygen. If you have four moles of Ba(OH)₂ you will have four times the amount that is found in one mole.

4 moles of Ba(OH)₂ will have 8 moles of oxygen.

The number of moles of oxygen atoms we have in the compound is 8 moles .

The chemical equation for barium hydroxide is as follows:

Ba(OH)₂

According to the compound we have 1 atom of barium, 2 atoms of oxygen and 2 atoms of hydrogen.

Therefore, 4 moles of the compound can be represented as follows;

4 Ba(OH)₂

This means we have 4 atoms of barium, 8 atoms of oxygen and 8 atoms of hydrogen.

Therefore, we have  8 moles of oxygen atoms or 4 moles of oxygen molecules.

Explanation:

Renewable energy resources refers to energy resources  that can not be depleted such as wind, solar, biomass etc.

Non-renewable energy resources refers to those energy resources that can be depleted such as fossil fuels.

Globally, it has been established that energy from renewable sources costs less than energy from nonrenewable(especially fossil fuel) sources.

According to Forbes, 2019, "The worldwide weighted average cost of electricity from solar power concentration fell by 26%, that of bioenergy reduced by 14%, solar photovoltaics, geothermal, onshore, as well as offshore wind, fell by 14%, and hydropower by 12%.".

This shows us that renewable energy remains the cheapest alternative in terms of energy cost.
