How many cm3 are contained in 3.83 x 107 mm3?

gulaghasi [49]

Answer:

3.38 x 10⁴cm³

Explanation:

Given that:

Volume of the substance = 3.83 x 10⁷mm³

The problem entails use to convert from mm³ to cm³;

1000mm³ = 1cm³

So;

3.83 x 10⁷mm³ will produce $\frac{ 3.83 x 10^{7} }{1000}$ = 3.38 x 10⁴cm³

What types of emergency situations could rescue workers be in that would make it difficult for them to get energy to their elect

artcher [175]

Answer:

Large-scale natural disasters

Explanation:

The emergency situation that rescue workers could be in that would make it difficult for them to get energy to their electrical devices is "Large-scale natural disasters"

Large-scale natural disasters are very destructive and devastating. Their impact and effect can range from destruction of infrastructures, properties, social amenities and even ecosystems. When such disasters break out, they destroy things and which leads to difficulty in accessing certain amenities. Rescue workers even find it difficult to access energy for their electrical devices - because there is power outage.

Some of these large-scale natural disasters are earthquakes, tornadoes, hurricanes, floods, etc.

Consider the following chemical reaction in a small volume of solution. According to LeChatelier’s Principle, which perturbation

stiks02 [169]

Answer:

Decreasing the temperature will shift the equilibrium leftwards towards reactants.

Explanation:

Hello!

In this case, since the reaction between chromate anions and hydrogen ions yields dichromate anions, water and heat, we can infer this is an exothermic reaction by which heat is released (remember in endothermic reactions heat is absorbed as a reactant), it means that considering the LeChatelier’s which states that increasing the temperature of an exothermic reaction shifts the equilibrium leftwards since heat is a product, otherwise (decreasing the temperature) the equilibrium will be shifted rightwards.

Therefore, decreasing the temperature is the perturbation that will shift the equilibrium leftwards towards the reactants.

Best regards!
