Common hydrogen compounds

Hydrogen combines with other elements, forming a number of compounds, including common ones such as water (H2O), ammonia (NH3), methane (CH4), table sugar (C12H22O11), hydrogen peroxide (H2O2) and hydrochloric acid (HCl), according to Jefferson Lab.

Answer:

letter A.

Explanation:

the rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. this is done by cutting the substance into small pieces, or by grinding it into a powder.if the surface area of a reactant is inceased: more particles are exposed to the other reactant.

Answer:

C. Transition metals

Explanation:

Out of the answers transition metals have the most elements on the periodic table.    

Answer:

4

Explanation:

There are 4 different elements in the compound (N, H, P, O) but if you want to count the number of each element then the answer is different.

In NH4, theres 1 N and 4 H, but since there are 3 NH4s then u have 3 N and 12 H. There's 1 P and 4 Os as well.

Added together u have 3 + 12 + 1 + 4 = 20 elements in total.

Answer:

Explanation:

The process is photosynthesis as plants need carbon dioxide and humans need oxygen so plants release oxygen which humans breath/take in and plant/trees take in carbon dioxide which humans release.

The natural process which removes  carbon dioxide from the atmosphere is photosynthesis.

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

The special cases of gas laws and its description includes:

A. Boyle's law: P1 V1 = P2 V2

B. Charles's law: V/T = k or V1 / T1 = V2 / T2

C. Avogadro's law: V = kn

D. Dalton's law: Ptotal = P1 + P2 + P3 + .

Gas laws are laws that relate a gas's pressure, volume, and temperature. Boyle's law, named after Robert Boyle, states that the pressure P of a gas varies inversely with its volume V at constant temperature, or PV = k, where k is a constant. Charles' law is named after J. -A. -C.

Answer: The enthalpy change for this reaction is, -803 kJ

Explanation:

The balanced chemical reaction is,

[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)[/tex]

The expression for enthalpy change is,

[tex]\Delta H=\sum [n\times \Delta H_f(product)]-\sum [n\times \Delta H_f(reactant)][/tex]

[tex]\Delta H=[(n_{CO_2}\times \Delta H_{CO_2})+(n_{H_2O}\times \Delta H_{H_2O})]-[(n_{O_2}\times \Delta H_{O_2})+(n_{CH_4}\times \Delta H_{CH_4})][/tex]

where,

n = number of moles  

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

[tex]\Delta H=[(1\times -394)+(2\times -242]-[(2\times 0)+(1\times -75)][/tex]

[tex]\Delta H=-803kJ[/tex]

Therefore, the enthalpy change for combustion of methane is, -803 kJ

Answer:

19.32 = moles of carbon

57.54 = moles of hydrogen

9.69 = moles of oxygen

Explanation:

232 g carbon × 1 mol C / 12.011 g C= 19.32 mol C

58 g hydrogen × 1 mol H / 1.008 g H = 57.54 mol H

155 g oxygen × 1 mol O / 15.999 g O = 9.69 mol O

Answer:

coevolution

Explanation:

Coevolution plays a key role in shaping the biodiversity on Earth. Coevolution is commonly defined as reciprocal evolutionary changes brought about by interactions between species, implying that interacting species impose selection on each other(Science direct).

We can see that the change that occurred in the plants of the tropical rainforests is closely related to their link to birds. The fruits evolved an attractive color so that birds, having evolved to eat the brightly-colored fruits, may eat them.

As in the given image, the weather pattern known as Arizona monsoon is caused by the winds at this latitude tend to blow from west to east. Thus, option C is correct.

The Arizona Monsoon is a well-defined meteorological phenomenon that affects the southwest region of North America during the summer. It is scientifically referred to as a meteorological "singularity."

Arizona experiences its strongest wind flow during the winter months from the west or northwest, coming from California and Nevada. The winds change to a southerly or southeasterly direction as the summer months approach.

From the Pacific Ocean and the Gulf of Mexico, moisture moves northward. Statewide moisture conditions are drastically altered as a result of this alteration.
