Answer:When two plates travel in the same direction, they intersect or collide. A convergent boundary is a collision between two plates that are traveling in the same direction. Large damaging earthquakes occur from the collision. The forming of massive folded mountains occurs as two continental plates collide.

Answer: The pH of resulting solution is 14.

Explanation:

pH of a solution is the negative logarithm of concentration of hydrogen ions.

If two or more solutions are mixed together then pH of the resulting solution is calculated as the sum of pH of all the solutions.

As pH of a given solution is 2 and pH of another solution is 12. Therefore, pH of the resulting solution is calculated as follows.

[tex]pH = pH_{1} + pH_{2}[/tex]

where,

[tex]pH_{1}[/tex] = pH of solution 1

[tex]pH_{2}[/tex] = pH of solution 2

Substitute the values into above formula as follows.

[tex]pH = pH_{1} + pH_{2}\\= 2 + 12\\= 14[/tex]

Thus, we can conclude that the pH of resulting solution is 14.

my advice is split the equation into 2 and write on each side how many atoms of each element are there and it will be easier to balance.

Answer:

D is the answer

Explanation:

Because thermal is Heat Energy

I hope it's right

Thermal energy is the energy associated with temperature. The correct option is d.

Thermal energy is the energy associated with a substance's or system's temperature. It is a type of kinetic energy that results from the random motion of tiny particles.

The higher the temperature, the larger the average kinetic energy of the particles and the bigger the amount of thermal energy present.

Heat transmission, phase shifts (such as melting or boiling), and the general thermal behaviour of materials all require thermal energy.

It differs from other types of energy including electrical energy (option a), chemical potential energy (option b), and gravitational potential energy (option c).

Thus, the correct option is d.

Answer:

partial pressure of gas D Pd = 15.5 kPa

Explanation:

As per the Dalton's law of partial pressure, in a mixture, pressure exerted by each gas when summed gives the total partial pressure exerted by mixture.

P(Total) = P1+P2+P3.....

Given P(Total) = 35.7 kPa

Partial pressure of gas A Pa = 7.8 kPa

Partial pressure of gas B Pb = 3.7 kPa

Partial pressure of gas C Pc =  8.7 kPa

There, Partial pressure of gas D Pd = P(Total) -(Pa+Pb+Pc)

Pd = 35.7-(7.8+3.7+8.7) = 35.7-20.2 kPa = 15.5 kPa

Therefore, partial pressure of gas D Pd = 15.5 kPa

Answer:

The restoring force that prevents the furniture from tipping over when pushing the furniture towards the right, F= W × D

Where;

W = The weight of the furniture

D = The horizontal distance from the center of gravity of the furniture, CG and the to the lower right corner of the furniture

Given that A > D, for the furniture to tip over when pushing above the CG, we have;

F1 × A ≤ W × D

∴ F1 << W or for a force much smaller than W, the weight of the furniture applied above the center of gravity, the furniture will tip over

However when the force F2 is applied, where C < D, we have for no tipping over;

F2 × C ≤ W × D, therefore, given that C < D, when a force much higher than the weight, W, is applied at F2, the furniture will remain upright

Therefore, it is better push at a point lower than or equal to the center of gravity, whereby the point B is lower than the center of gravity, it is better to push at point B, Ravleen is correct and it is better to push at point B because the center of gravity is lower

If the furniture is pushed at the wrong spot it may tip over

44.5 g Al2(SO4)3

Explanation:

# moles Ba(NO3)2 = (0.543M)(0.717 L)

= 0.389 mol Ba(NO3)2

Now we use the molar ratios,

0.389 mol Ba(NO3)2 ×(1 mol Al2(SO4)3/3 mol Ba(NO3)2)

= 0.130 mol Al2(SO4)3

0.130 mol Al2(SO4)3 × (342.15 g Al2(SO4)3/(1 mol Al2(SO4)3)

= 44.5 g Al2(SO4)3

Answer:

0.11 moles

Explanation:

The equation of the reaction is;

2SO2 + O2 ------>2SO3

Number of moles of O2 in 3.42 g = 3.42g/32 g/mol = 0.11 moles

Hence, 0.11 moles of O2 is consumed when 3.42 g of O2 reacts with SO2 to form SO3.

1.39 g HCl

Explanation:

The balanced chemical equation for this reaction is given by

Zn(s) + 2HCl(aq) ---> ZnCl2(aq) + H2(g)

Convert the # of grams of Zn to moles:

1.25 g Zn × (1 mol Zn/65.38 g Zn) = 0.0191 mol Zn

Use the molar ratio to find the # of moles of HCl needed to react completely with the given amount of Zn:

0.0191 mol Zn × (2 mol HCl/1 mol Zn) = 0.0382 mol HCl

Convert this amount to grams:

0.0382 mol HCl × (36.458 g HCl/1 mol HCl) = 1.39 g HCl

Answer:

7200 kPa

Explanation:

Applying,

PV/T = P'V'/T'................ Equation 1

Where P = Initial pressure of neon gas, V = Initial volume of neon gas, T = Initial temperature of neon gas, P' = Final pressure of neon gas, V' = Final volume of neon gas, T' = Final Temperature of neon gas

Make P' the subject of the equation

P' = PVT'/V'T.............. Equation 2

Given: P = 900 kPa, V = 8.0 L, T = 300 K, V' = 2.0 L, T' = 600 K

Substitute these values into equation 2

P' = (900×8×600)/(2×300)

P' = 7200 kPa

Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.

Explanation:

The key components of nitrogen cycle are :nitrogen fixation, nitrification, assimilation, ammonification and denitrification.

It is a bio-geochemical cycle through which nitrogen is converted into multiple chemical forms when it circulates among atmospheric, terrestrial  and marine ecosystems .

Conversion of nitrogen is carried out through physical and biological processes.Nitrogen cycle is important as it affects of ecosystem processes like primary production and decomposition.

Conversion of nitrogen gas to nitrates and nitrites through atmospheric , industrial and biological processes is called nitrogen fixation. Nitrogen is assimilated in plants in form of nitrates or ammonium forms.When an animal or plant dies the nitrogen in organic form is converted to ammonium which is mineralization.

Answer:

1. Allele for shortness (t)

2. Allele for tallness (T)

Explanation:

Gregor Mendel performed numerous experiments using pea plants (Pisium sativum). He tested the height traits of pea plants by crossing tall pea plants (TT) and short pea plants (tt) to obtain offsprings that were all tall (Tt) in the first filial generation (F1).

This is possible because the allele for tallness is DOMINANT while the allele for shortness is RECESSIVE. This means that tallness allele (T) will mask the phenotypic expression of shortness allele (t) when in an heterozygous state (Tt) as in the F1 generation.
