Answer:

As the garter snake can be found almost in any kind of habitat, what makes them be able to survive in any environment include:

1. They hibernate to increase their chances of survival in unfavorable weather conditions.

2. They can blend with the background of any environment especially grass to escape being eaten.

3. They produce an odor that is usually unpleasant especially when about to be attacked.

Explanation:

The garter snakes are distinguished by the three stripes running the length of their body and can often be found in forests, places that are even close to water bodies, and almost any place, even in holes.

The vapor pressure of diethyl ether (ether) is 463.57 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in diethyl et

Molodets [167]

Answer:

Explanation:

The vapor pressure of diethyl ether (ether) is 463.57 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in diethyl ether is aspirin. Calculate the vapor pressure of the solution at 25 °C when 14.88 grams of aspirin, C9H8O4 (180.1 g/mol), are dissolved in 269.2 grams of diethyl ether. diethyl ether = CH3CH2OCH2CH3 = 74.12 g/mol.

mol of C4H10O = mass of C4H10O / molar mass of C4H10O

= 242.1 g / 74.12 g/mol

= 3.266 mol

mol of C9H8O4 = mass of C9H8O4 / molar mass of C9H8O4

= 10.33 g / 180.1 g/mol

= 0.05736 mol

mole fraction of C4H10O,

X = mole of CHH1O0 / total mol

= (3.266)/(3.266 + 0.05736)

= 0.9827

now use:

P = Po*X

P = 463.57 * 0.9827

= 455.6 mm Hg

2. If a machine produces 225 parts in an 8 hour day, how many minutes will it take to

vekshin1

21.28s

Explanation:

This is a rate problem.

Number of parts produced = 225

Time taken to produce= 8hours

Rate of production is the amount of parts produced in a duration of time.

Now convert 8 hours to minute;

60 minutes = 1hr

8 hours = 60 x 8 = 480minutes

Now:

Rate of production = $\frac{225 parts}{480min}$ = 0.47parts/minute

Now, to produce 10 parts;

It takes;

0.47 parts to be produced in 1 minute

10 parts would be produced in $\frac{10}{047}$ = 21.28s

A mixture containing KClO3,K2CO3,KHCO3, and KCl was heated, producing CO2,O2, and H2O gases according to the following equations

Nikitich [7]

Answer:

For 1: The mass of $KClO_3$ in the original mixture is 10.46 g

For 2: The mass of $KHCO_3$ in the original mixture is 21.11 g

Explanation:

We are given:

Mass of water = 1.90 g

Mass of carbon dioxide = 13.64 g

Mass of oxygen = 4.10 g

For 1:

The given chemical reaction for decomposition of $KClO_3$ follows:

$2KClO_3\rightarrow 2KCl+3O_2$

By Stoichiometry of the reaction:

$(3\times 32)=96g$ of oxygen is produced when $(2\times 122.5)=245g$ of potassium chlorate is decomposed.

So, 4.10 g of oxygen will be produced when = $\frac{245}{96}\times 4.10=10.46g$ of potassium chlorate is decomposed.

Amount of $KClO_3$ in the mixture = 10.46 g

For 2:

The given chemical reaction for decomposition of $KHCO_3$ follows:

$2KHCO_3\rightarrow K_2O+H_2O+2CO_2$

By Stoichiometry of the reaction:

18 g of water is produced when $(2\times 100)=200g$ of potassium bicarbonate is decomposed.

So, 1.90 g of water will be produced when = $\frac{200}{18}\times 1.90=21.11g$ of potassium bicarbonate is decomposed.

Amount of $KHCO_3$ in the mixture = 21.11 g

SO3 has how many regions of high electron density and how many bonded electrons when the octet rule is strictly obeyed?1.5; 142.

motikmotik

Answer:

3 regions of high electronic density

2 simple links

1 double bond

Explanation:

Hello!

First we calculate the total valence electrons that make up the molecule (6 + 6 * 3 = 24)

We locate six electrons forming the bonds and complete the octecs with the remaining 18 electrons.

We move 2 electrons of an oxygen to complete the sulfur octet.

An atom's atomic number is 7. Its valence is most likely ... An atom's atomic number is 7. Its valence is most likely ... 7 5 3

Naya [18.7K]

The valence of an atom is defined as the number of bonds formed by the atom in the molecule.

The given atomic number is 7.

The electronic configuration of atom having atomic number 7 is:

$1s^{2}2s^{2}2p^{3}$

From the electronic configuration, it is clear that number of electrons in the outer most orbital (valence shell electron) is 5.

Hence, for an atom whose atomic number is 7. Its valence is 5.
