Answer:

20.4 miles.

Explanation:

We know he usually rides his bike at 15mph, and if we subtract 3 from that we get 12 miles per hour. Now if we multiply by the amount of time (1.7 hours) we'll find our answer. 12 x 1.7 = 20.4

The phrase "Most ecosystems are solar powered" refers to the fact that most organisms seek sunlight. solar energy is converted t
Savatey [412]

Answer:

The solar energy is converted to chemical energy by the process of photosynthesis - This is the true statement of the given question.

Explanation:

An ecosystem usually refers to the biological community comprising all the types of living species that are continuously interacting with the surrounding environment. Most of these ecosystems are solar-powered, and by this phrase, it means that there occurs the transformation of energy from solar to chemical energy which is taking place due to the process of photosynthesis. Both the terrestrial and the aquatic, are able to carry out this process in the presence of sunlight, water, and CO₂, and in return, it liberates food and oxygen into the ecosystem.

Thus, this statement satisfies the given phrase.

All other options are false as it does not justify the phrase.

How many moles of calcium hydroxide, ca(oh)2, are needed to neutralize 2 moles of sulfuric acid, h2so4?
Ronch [10]
The balanced equation for the neutralisation reaction is as follows 
Ca(OH)₂ + H₂SO₄ ---> CaSO₄ + 2H₂O
stoichiometry of Ca(OH)₂ to H₂SO₄ is 1:1
equivalent number of acid reacts with base
number of H₂SO₄ mol reacting - 2 mol
according to molar ratio of 1:1
number of Ca(OH)₂ mol = number of H₂SO₄ moles 
therefore number of Ca(OH)₂ moles required - 2 mol

When an alkaline earth metal, a, reacts with a halogen, x, the formula of the covalent compund formed should be a2x?
Ierofanga [76]

Alkaline earth metal are the elements present in II group in the periodic table and are known as 'Metals' and have a charge of +2.

Alkaline earth metals - Be , Mg Ca, Sr , Ba, Ra

Halogens are present in VII A group in the periodic table and are 'Non-metals' and have a charge of -1.

Halogens - F, Cl, Br, I, At

When Alkaline earth metal (metals) combine with Halogens (non-metals) the compound formed will be ionic compound and the formula of the compound will be based on the charges of the element.

When we write the formula of the ionic compound the charges of the elements get criss crossed.

For example - Mg (Alkaline earth metal) have a charge of +2 and Cl (Halogen) have a charge of -1 and when they combine to form the formula their charges get criss crossed and we will get Mg_{1}Cl_{2} or MgCl_{2}

When an alkaline earth metal, A, reacts with a halogen, X, the formula of the Ionic compound formed should be AX_{2}
