Answer:
lost 2 electrons
Explanation:
A <em>cation</em> by definition is a positively charged ion. They are formed when a metal loses its electrons. A cation has more protons than electrons, giving it a net positive charge. So, it had to have lost 2 electrons to give it a positive charge of 2⁺.
Palisades is referred to a line of cliffs formed from eroded volcanic rock and is denoted as option C.
<h3>
What is a Cliff?</h3>
This is defined as a type of rock which is usually made of basalt , has a high vertical side and is usually very steep in slope.
Palisades are formed from eroded volcanic rocks which are present in water bodies such as rivers etc and acts a type of barrier and protection in the area such as the Hudson river in the United States.
This is therefore the reason why option C was chosen as the correct choice.

Explanation :
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The rule apply for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
(a) 628 × 342
The correct answer is,
(b) (5363 × 102) × (7.4 × 103)
The correct answer is,
(c) 28.0 ÷ 13.483
The correct answer is, 2.08
(d) 8119 × 0.000023
The correct answer is,
(e) 14.98 + 27,340 + 84.7593
The correct answer is,
(f) 42.7 + 0.259
The correct answer is,
Answer:
The answer is 0.844/10 minutes
Explanation:
You have an enzyme that catalizes a reaction which gives a product that can be quantified by an absorbance measurement. The more reaction time, the more product quantity and higher absorbance.
The rate of the reaction is the change in products quantity per time unit. As you are using the absorbance as a measure of the product quantity, you can calculate the rate as the change in absorbance (ΔA) per time (in minutes) as follows:
rate= ΔA/time
rate= (final absorbance - initial absorbance) /minutes
rate= (0.444-0.022)/5 min
rate= 0.422/5 min
In 10 minutes will be :
rate= 0.844/10 min
Commonly, a rate is the relation between two quantities measured in different units. For example, the speed of a car is the change in meters (traveled distance) per time (m/s or km/h). For an enzyme, is the same (quantity of product/time).
