Answer:

a. Solar

Explanation:

Solar energy causes water to evaporate, which is the driving force of the water cycle. Water from the ocean evaporates and comes back down as rain and it gives life to the Earth and so it continues.

Answer : A. Solar

Explanation : The sun provides its solar energy which causes liquid and frozen water to evaporate into water vapor. This water vapor rises into the sky to form clouds, and from there on the clouds move over the globe and drop rain and snow, and from there on the water cycle continues.

Grams of sodium 9.5g in NaCl <br>​
Kitty [74]

Answer:

3.68 grams.

Explanation:

First we <u>convert 9.5 g of NaCl into moles of NaCl</u>, using its<em> molar mass</em>:

9.5 g ÷ 58.44 g/mol = 0.16 mol NaCl

In<em> 0.16 moles of NaCl there are 0.16 moles of sodium </em>as well.

We now <u>convert 0.16 moles of sodium into grams</u>, using <em>sodium's molar mass</em>:

0.16 mol * 23 g/mol = 3.68 g

A group 2 metal carbonate has a mass of 84 g/mol. Identify the group 2 metal X using its chemical formula.
zepelin [54]

Answer:

Magnesium

0.003mole

Explanation:

The problem here entails we find the metal in the carbonate.

 For group 2 member, let the metal  = X;

 The carbonate is XCO₃;

 If we sum the atomic mass of the elements in the metal carbonate, we should arrive at 84g/mol

 Atomic mass of C = 12g/mol

                            O  = 16g/mol

 Atomic mass of X + 12 + 3(16)  = 84

  Atomic mass of X  = 84 - 60  = 24g/mol

The element with atomic mass of 24g is Magnesium

B.

Number of moles in 0.3g of CaCO₃:

     Molar mass of CaCO₃   = 40 + 12 + 3(16)  = 100g/mol

 Number of moles = \frac{mass}{molar mass}  

 Number of moles  = \frac{0.3}{100}   = 0.003mole

How are isotopes of the same chemical element alike? How are they different?
Stella [2.4K]

<u>Answer:</u> The atomic mass of these species is different and atomic number remains same.

<u>Explanation:</u>

Isotopes are the chemical species of the same element having different number of neutrons.

  • Atomic number is equal to the number of protons or electrons present in that element.

Atomic Number = Number of electrons = Number of protons

  • Atomic mass is defined as the sum of number of protons and neutrons contained in an atom.

Atomic Mass = Number of protons + Number of neutrons

For isotopes, as the number of neutrons differ, the atomic mass also differs.

For Example: Carbon has 3 naturally occurring isotopes: _6^{12}\textrm{C},_6^{13}\textrm{C}\text{ and }_6^{14}\textrm{C}. The atomic number remains the same but atomic mass differs.

Hence, for isotopes, the atomic mass of these species is different and atomic number remains same.

An allele whose trait shows up in an organism when the allele is present is a
dmitriy555 [2]

Dominant allele

Explanation:

An allele whose trait shows up in an organism when the allele is present is called a dominant allele.

An allele whose trait does not show up in an organism when present is called a recessive allele.

  • An allele is the two possible forms of gene.
  • A gene can be dominant or recessive in nature.
  • An allele is a DNA that occupies a particular locus on a chromosome.
  • They usually occur in pairs.
  • The allele determines hereditary characteristics.
