If a fish gets squirted with ink it will swim slower

In what ways are the two designs in part C different? How do you think these differences will relate to the ability of each desi

Ilya [14]

The top one is different from the bottom because of is curvature shape while the bottom one is a square shape i think the bottom will heat up faster because of the nice even area inside where heat waves can evenly flow

Which compound contains ionic bonds? 1. N₂O 2.Na2o 3. co 4.CO2

Molodets [167]

Answer:
2. Na2O

Reasoning:
Na (soduim) is the only metal out of all the elements in the answer choices, and is bonded with oxygen, a nonmetal, therefore creating an ionic bond.

What would be the change in pressure in a sealed 10.0 l vessel due to the formation of n2 gas when the ammonium nitrite in 2.40

larisa86 [58]

The change in pressure in a sealed 10.0L vessel is 5.28 atm

calculation

The pressure is calculated using the ideal gas equation

That is P=n RT

where;

P (pressure)= ?

v( volume) = 10.0 L

n( number of moles) which is calculated as below

write the equation for decomposition of NH₄NO₂

NH₄NO₂ → N₂ +2H₂O

Find the moles of NH₄NO₂

moles = molarity x volume in liters

= 2.40 l x 0.900 M =2.16 moles

Use the mole ratio to determine the moles of N₂

that is from equation above NH₄NO₂:N₂ is 1:1 therefore the moles of N₂ is also =2.16 moles

R(gas constant) =0.0821 l.atm/mol.K

T(temperature) = 25° c into kelvin = 25 +273 =298 K

make p the subject of the formula by diving both side by V

P = nRT/V

p ={ (2.16 moles x 0.0821 L.atm/mol.K x 298 K) /10.0 L} = 5.28 atm.

Somebody help me with this please very much appreciated

Flauer [41]

The answer for the following answer is explained below.

The answer is NH_{4} ^{+}

Explanation:

Bronsted-Lowry acid :

It is a solution that donates protons, and is known as a proton donor.It donates protons in the form of hydrogen ion( $H^{+}$ ).This is reinforced by the definition of an acid ,which is a solution that has hydrogen ions.

In Bronsted-Lowry aci it must contain a hydrogen io that it can give up.When the acid gives a hydrogen ion,the charge of an acid decreases.

Here,

NH_{4} ^{+} loses one hydrogen ion and forms ammonia molecule.

So therefore the Bronsted-Lowry acid is NH_{4} ^{+}.

What is the physical process whereby atoms or molecules tend to move from an area of higher concentration or pressure to an area

34kurt

Diffusion is the physical process whereby atoms or molecules tend to move from an area of higher concentration or pressure to an area of lower concentration or pressure.

In the field of science, diffusion can be described as a process in which molecules move along the concentration gradient i,e from a region of higher concentration to a region of lower concentration.

The process of diffusion is extremely useful in many everyday living conditions. For example, it is due to diffusion that carbon dioxide and oxygen are exchanged between the lungs and the blood. Diffusion of water, salts, and water is an important process that occurs in the kidneys.

We can divide diffusion into two main types which are simple diffusion and facilitated diffusion. Simple diffusion occurs without any carrier molecule. On the other hand, facilitated diffusion occurs with aid of a carrier molecule.
