Chemistry
1 answer:
Elanso [62]2 years ago
7 0

Based on the information provided in this image shown above, the measurement to two (2) significant figures is equal to 3.50 mm.

<h3>What is measurement?</h3>

Measurement can be defined as an act or process through which the size, magnitude, dimensions, or distance traveled by a physical object or body is taken, especially for the purpose of an experiment.

<h3>What is a scale of measurement?</h3>

A scale of measurement can be defined as a classification which is used to illustrate the attributes of the values that are assigned to variables associated with a data set.

<h3>What is a significant figure?</h3>

In Mathematics, a significant figure can be defined as the number of digits in a numerical data (value), typically a measurement, which enhances its degree of accuracy.

Based on the information provided in this image shown above, the measurement of the film to two (2) significant figures is equal to 3.50 mm.

Where in an equation for photosynthesis does oxygen belong?
LUCKY_DIMON [66]

Answer:

on the right side, because it is a product

Explanation:

photosynthesis is the chemical reaction with the help of which plants produce chemical energy with the help of light energy.

_______________________________________________

The general standard for writing chemical reaction is that

  • The chemical which are input to the process of chemical reaction are written on left hand side . They are known as reactant.
  • The output of chemical reaction are written on right side. They are termed as product.
  • Transition of reactant to product is shown by arrow.

Chemical reaction for photosynthesis is given by below equation

6CO2 + 12H2O  + light ----------------> C6H12O6 + 6O2 + 6H2O  

We can see that 6 molecules of light combines with 12 molecules of water to give one molecule of glucose and 6 molecules of both water and oxygen.

As, oxygen is the output of photosynthesis process, it is written on the right-hand side of equation and is product of this reaction.

.

Thus, of the options given below for

In an equation for photosynthesis does oxygen belong

on the right side, because it is a product

175 ml of a 1.6 m solution of kcl is diluted to a new volume of 1.0 l. what is the new concentration of the solution? (3 points)
djyliett [7]

175 ml of a 1.6 m solution of KCl is diluted to a new volume of 1.0 L. The new concentration of the solution is 0.28 m KCl.

Hence, Option (B) is correct answer.

<h3>What is Concentration ?</h3>

Concentration is defined as the measure of how much substance there is mixed with another substance.

<h3>How to find the concentration ?</h3>

To find the concentration use the dilution formula

C₁V₁ = C₂V₂

where,

C₁ = Concentration of starting solution

C₂ = Concentration of final solution

V₁ = Volume of the starting solution

V₂ = Volume of the final solution

Now put the values in above formula we get

C₁V₁ = C₂V₂

1.6 × 0.175 = C₂ × 1.0

0.28 = C₂ × 1.0

C₂ = 0.28

Thus from the above conclusion we can say that 175 ml of a 1.6 m solution of KCl is diluted to a new volume of 1.0 L. The new concentration of the solution is 0.28 m KCl.

Hence, Option (B) is correct answer.

Which is a potential benefit of genetic engineering in agriculture​
lorasvet [3.4K]
Genetic alterations made to an organisms DNA would cause the synthesis of certain proteins that would lead to improvement in that organism’s ability to survive in and through specific components of its environment.

In the context of agriculture, potential benefits of genetic engineering include allowing agricultural organisms to thrive in any environment they were to be grown in, and to fight and persist against biological threats, such as a harmful bacteria.

Overall, potential benefits of genetic engineering in agriculture can be summarized improving the agricultural industry: higher productivity, quality, and efficiency of the crops.
