How does a hydra move?....In short form​

Chemistry
2 answers:
Bond [772]3 years ago
6 0

Answer:

Hydras are typically sessile, however they are able to detach and flow to every other place via way of means of gliding slowly on their base. Sometimes they somersault, float, or use their tentacles to transport along. ... If reduce into numerous sections, a brand new Hydra will generate from every piece.

Answer:

Hydras are generally sessile, but they can detach and move to another location by gliding slowly on their base. Sometimes they somersault, float, or use their tentacles to move along. ... If cut into several sections, a new Hydra will generate from each piece.

How long will it take a plane to go 800 miles if it’s traveling at an average speed of 650 miles per hour?
Naya [18.7K]

If there is NO wind resistance, just plain math, this is the answer.

To get the answer you would divide 800 by 650.

800/650 = 1.230769231 (exactly)

That would translate to exactly <span>1 hour 13 minutes and 50 seconds </span>

Arrange the compounds in order of decreasing magnitude of lattice energy:
Alik [6]

Answer:

The correct answer is CaO > LiBr > KI.

Explanation:

Lattice energy is directly proportional to the charge and is inversely proportional to the size. The compound LiBr comprises Li+ and Br- ions, KI comprises K+ and I- ions, and CaO comprise Ca²⁺ and O²⁻ ions.  

With the increase in the charge, there will be an increase in lattice energy. In the given case, the lattice energy of CaO will be the highest due to the presence of +2 and -2 ions. K⁺ ions are larger than Li⁺ ion, and I⁻ ions are larger than Br⁻ ion.  

The distance between Li⁺ and Br⁻ ions in LiBr is less in comparison to the distance between K⁺ and I⁻ ions in KI. As a consequence, the lattice energy of LiBr is greater than KI. Therefore, CaO exhibits the largest lattice energy, while KI the smallest.

For the following reaction, 33.7 grams of bromine are allowed to react with 13.0 grams of chlorine gas.
Ira Lisetskai [31]

Explanation:

The reaction is given as;

Br2(g) + Cl2(g) ----> 2BrCl(g)

From the equation;

1 mol of Br2 reacts with 1 mol of Cl2

Converting the masses given to moles, using the formular;

Number of moles = Mass / Molar mass

Br2;

Number of moles = 33.7 g / 159.808 g/mol = 0.21088 mol

Cl2;

Number of moles = 13.0 g / 70.906 g/mol = 0.18334 mol

From the values;

0.18334 mol of Cl2 would react with 0.18334 mol of Br2 with an excess of 0.02754 mol of Br2

<em>What is the maximum amount of bromine monochloride that can be formed? __________grams</em>

<em />

1 mol of Cl2 produces 2 mol of Bromine Monochloride

0.18334 mol of Cl2 would produce x

Solving for x;

x = 0.18334 * 2 = 0.36668 mol

Converting to mass;

Mass = Number of moles * Molar mass = 0.36668 mol * 115.357 g/mol

Mass = 42.299 g

<em />

<em>What is the FORMULA for the limiting reagent?</em>

<em />

The limiting reagent is Cl2 as it determines the amount of product formed. The moment the reaction uses up Cl2, the reaction stops.

<em>What amount of the excess reagent remains after the reaction is complete? __________grams</em>

The excess reagent is Br2

The number of moles left is;

0.02754 mol of Br2

Converting to mass;

Mass = Number of moles * Molar mass = 0.02754 mol  * 159.808 g/mol

Mass = 4.401 g

The difference between simple diffusion and facilitated diffusion is that facilitated diffusion
Sholpan [36]

Answer:

Simple and facilitated diffusion are both similar types of phenomenon where the substances are moved from a region of high concentration to lower concentration across a semi-permeable membrane.

The main difference between them is that the facilitated diffusion requires a special type of protein or carrier molecules in order to transport the substances whereas simple diffusion does not require such molecules. The rate of flow of these substances is high in the facilitated diffusion in comparison to the simple diffusion.
