Answer: Other nonmetal elements are oxygen, neon, fluorine, nitrogen, carbon, boron, chlorine, argon, and hydrogen.

Explanation:

If you look at the periodic table the elements are grouped together. For example the metals are in the middle, the nonmetals are on either sides (noble gases, earth alkaline, reactive nonmetals, and etc.)

At a certain temperature the rate of this reaction is first order in SO₃ with a rate constant of 0.208 s⁻¹:

NNADVOKAT [17]

Answer:

0.30 M

Explanation:

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

Where,

$[A_t]$ is the concentration at time t = ?

$[A_0]$ is the initial concentration = 1.36 M

k is the rate constant = 0.208 s⁻¹

t = 7.30 seconds

So,

$[A_t]=1.36\times e^{-0.208\times 7.30}\ M=0.30\ M$

What is the molality of a solution if 100.0 g of glucose (C&Hi20e) were dissolved into 750. mL of water?

hodyreva [135]

Answer: The molality of solution is 0.740 m.

Explanation:

To calculate the mass of solvent (water), we use the equation:

$Density=\frac{Mass}{Volume}$

Volume of water = 750 mL

Density of water = 1 g/mL

Putting values in above equation, we get:

$1g/mL=\frac{\text{Mass of water}}{750mL}\\\\\text{Mass of water}=750g$

To calculate the molality of solution, we use the equation:

$Molarity=\frac{m_{solute}\times 1000}{M_{solute}\times W_{solvent}\text{ in grams}}$

Where,

$m_{solute}$ = Given mass of solute $(C_6H_{12}O_6)$ = 100.0 g

$M_{solute}$ = Molar mass of solute $(C_6H_{12}O_6)$ = 180 g/mol

$W_{solvent}$ = Mass of solvent (water) = 750 g

Putting values in above equation, we get:

$\text{Molality of }C_6H_{12}O_6=\frac{100\times 1000}{180\times 750}\\\\\text{Molality of }C_6H_{12}O_6=0.740m$

Hence, the molality of solution is 0.740 m.

G brønsted-lowry proton transfer reaction, hydroxide functions as a/an ______.

Katen [24]

In a bronsted lowry proton transfer reaction, the hydroxide functions as a/an proton acceptor.

Bases are the opposite of acids. Bases are basic since they take or accept protons. For example, a Hydroxide ion can accept a proton to form water.
