Mass percentage of sodium chloride(NaCl) in ocean waters = 3.5 %

That means 3.5 g sodium chloride(NaCl) is present for every 100 g of ocean water.

The given mass of sodium chloride(NaCl) is 45.8 g

Calculating the mass of ocean waters that would contain 45.8 g sodium chloride(NaCl):

$45.8 g NaCl *\frac{100g ocean water}{3.5g NaCl}$

= 1309 g ocean water

Therefore, 45.8 g sodium chloride is present in 1309 g ocean water.

A scientist has isolated a fatty acid that has 26 carbons. Most of the carbon atoms in the fatty acid chain are connected by sin

igomit [66]

Answer:

Polyunsaturated

Explanation:

A fatty acid is a compound that is derivative from a carboxylic acid. The chain of carbons can have since 4 carbons to more than 20 carbons. The bonds between carbons can be simple, which are called saturated bonds, or double, or triple, which is called unsaturated bonds.

When a fatty acid only has saturated bonds between carbons, it's called a saturated fatty acid. If there is only one unsaturated bond, it's called an unsaturated fatty acid, and if there are two or more unsaturated bonds, it's called polyunsaturated fatty acid.

Which sentences describe alpha particles?

kakasveta [241]

Answer:

1. Alpha particles consist of two protons and two neutrons.

Explanation:

Alpha particles are generally produced in the process of alpha decay, a radio active decay in which an atom loses an helium atom.

AN alpha particle is identical to the helium particle. The helium particle has mass number of 4 and atomic number of 2. This means;

Number of protons = 2

Number of neutrons = Mass Number - Atomic Number = 2

The correct option is option 1.

1) Chemical reaction: CH₄ + H₂O → 3H₂ + CO ΔH = + 206 kJ/mol.
2) Chemical reaction: CO + H₂O → CO₂ + H₂, ΔH = + 2,8 kJ/mol.
3) Chemical reaction: CH₄ + 2O₂ → CO₂ + 2H₂O ΔH = -802 kJ/mol.
4) Chemical reaction: 2H₂ + O₂ → 2H₂O ΔH = 2·(-242 kJ7mol) = - 484 kJ/mol.

2. In contrast to Venus, the coldest temperature yet measured on the surface of

Leviafan [203]

38K

-391°F

Explanation:

Given temperature:

Temperature of Triton = -235°C

Unknown:

Surface temperature of Triton in °F and Kelvin

Solution:

Temperature is the degree of hotness or coldness of a body.

It is usually measured using units of kelvin, degree Celsius and degree Fahrenheit.

tK = 273 + t°C from °C to K

t°F = $\frac{9}{5}$ t°C + 32

tk = temperature in kelvin

t°C = temperature in Celsius

t°F = temperature in Fahrenheit

tK = 273 + (-235) = 38K

t°F = $\frac{9}{5}$ x (-235) + 32 = -423 + 32 = -391°F
