Answer:

.300M

Explanation:

It is necessary for us to remember that increasing the reactant concentration increases the rate of reaction. This is because reactant concentration is one of the most important factors that affects the rate of reaction.

Reactant concentration affects the rate of reaction because according to collision theory, chemical reaction results from effective collisions between reactants. Hence, if there are more reactants in the system, there are greater chances of effective collisions between the reactants.

Since 0.300M is a higher concentration than 0.2000M, the rate of reaction will increase when a 0.3000M solution is used.

The recommended application for dicyclanil for an adult sheep is 65 mg/kg of body mass. If dicyclanil is supplied in a spray wit
babunello [35]

Answer:

91 millilitres

Explanation:

Recommended application = 65mg / Kg

This means 65 mg of dicyclanil per kg (1 kg of body mass).

Concentration = 50 mg / mL

How many millilitres required to treat 70kg adult?

If 65mg = 1 kg

x = 70 mg

x = 70 * 65 = 4550 mg

Concentration = Mass / Volume

50 mg/mL = 4550 / volume

volume = 4550 / 50 = 91 mL

If we increase the temperature of the reaction that occurs in plants to create sugar. What direction does the equilibrium shift.
maxonik [38]

The reaction used to produce sugar in plants is Photosynthesis,

6CO₂ + 6H₂O + heat ⇆ C₆H₁₂O₆ + 6O₂↑

we can see that this reaction is endothermic, it absorbs heat to occur

If we were to add more heat or increase the temperature, the left side of the equilibrium will be able to react much more, which would produce more glucose (aka sugar)

Hence increasing the temperature will shift the equilibrium to the right or towards the Products
