grin007 [14]2 years ago
4 0

Only coniferous trees have thin, waxy, needle-like leaves that drop throughout the year and help to retain water.

<h3>What are coniferous trees?</h3>

Coniferous trees are evergreen trees that produce cones.

In addition, they produce waxy and needle-like leaves that help them conserve water by limiting the evapotranspiration rate as a result of reduced surface area.

Examples of conifers include pine trees and spruces.

In a chemical reaction, 36 grams of hydrochloric acid reacts with 40 grams of sodium hydroxide to produce sodium chloride and wa
Elena L [17]
The answer is <span>The mass of sodium chloride formed is less than 76 grams.
</span>
Remember Mass is never gained or loss in any chemical reactions

So,

hydrochloric acid  + sodium hydroxide  =>  <span>sodium chloride + water
                          Total 76 gram                         Total will also 76 gram

In this case, the mass of sodium chloride will be less than 76 gram because we need to take out the mass of the water.

A balloon is filled with 2000 mL of air at a pressure of 2 atm. What is the volume of the balloon if the pressure is
artcher [175]

Answer:

800mL

Explanation:

Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant

P1V1= P2V2

P1 = 2 atm, V1 = 2000mL ,

P2 = 5atm , V2 = ?

2 × 2000 = 5 × V2

Divide both sides by 5

V2 = 4000 ÷ 5

V2 = 800mL

135 grams of sodium has ______ moles.<br><br> (Enter just the number for this one.)
just olya [345]

Answer : 135 grams of sodium has 5.869 moles.

Solution : Given,

Mass of sodium = 135 grams

Molar mass of sodium = 23 g/mole

Formula used :

\text{Moles of sodium}=\frac{\text{Mass of sodium}}{\text{Molar mass of sodium}}

Now put all the given values in this formula, we get

\text{Moles of sodium}=\frac{135g}{23g/mole}=5.869moles

Therefore, the moles of sodium present in 135 grams of sodium is, 5.869 moles.

When atp is hydrolyzed to power a condensation reaction, what happens to the phosphate molecule that is released?
Leto [7]

The phosphate molecule that is released it is coupled to a different ADP molecule to make new molecule of ATP.

Hydrolysis of high-energy compound (ATP) using water:

ATP + H₂O → ADP + Pi

ATP is short for adenosine triphosphate.

Hydrolysis is a reaction that breaks down the chemical bonds between molecules via the addition of a water molecule.

A condensation reaction is a reaction that joins two molecules in a chemical bond.

ATP is resynthesized in a condensation reaction that adds an inorganic phosphate group to ADP. The addition of a phosphate group is catalyzed by the enzyme ATP synthase.

A 0.1375-g sample of solid magnesium is burned in a constant-volume bomb calorimeter that has a heat capacity of 3024 J/°C. The
Anna35 [415]

Answer:

-24.76 kJ/g; -601.8 kJ/mol

Explanation:

There are two heat flows in this experiment.

Heat from reaction + heat absorbed by calorimeter = 0

             q1                +                     q2                         = 0

           mΔH             +                    CΔT                        = 0

Data:

m = 0.1375 g

C = 3024 J/°C

ΔT = 1.126 °C

Calculations:

0.1375ΔH + 3024 × 1.126 = 0

           0.1375ΔH + 3405 = 0

                        0.1375ΔH = -3405

                                   ΔH = -24 760 J/g = -24.76 kJ/g

ΔH = -24.76 kJ/g ×24.30 g/mol = -601.8 kJ/mol
