1.54 x 10⁶kW
Explanation:
The problem here is converting from megawatts into kilowatts.
Given 1540megawatts.
The mega- and kilo- watts are prefixes that denotes multiples of units.
1 megawatt = 10⁶watts
1 kilowatt = 10³watts
Now given 1540megawatts power to Kilowatt power;
We see that :
1000kW = 1mW
1540mW x 
= 1.54 x 10⁶kW

Answer:
B. The motorcyclist traveled southeast along a highway at 55 mph and reached the campsite in less than the two-hour estimated time.
Explanation:
<em>Velocity </em>is the rate at which an object changes position in a specific direction. It has both <em>magnitude and direction.</em>
Travelling <em>southeast</em> at <em>55 mph</em> is a <em>velocity</em>. It gives both speed and direction.
Statements A., B., and C. give the direction but not the speed.
As you can see in the picture we have +ΔH so that means for this reaction we need to GET heat. so the answer is A. endothermic :))
i hope this is helpful
have a nice day
Answer:
option A is correct ( sodium, calcium and barium)
Explanation:
Given compounds:
Sodium chloride , calcium sulfide, barium oxide
We know that metals form positive ions. In order to solve the problem we must identify the metals from given compounds.
Na⁺Cl⁻
Ca²⁺S²⁻
Ba²⁺O²⁻
We can see that sodium, calcium and barium contain positive charges.
Thus option A is correct.
Because sodium have one valance electron. When it combine with chlorine sodium lose its one electron to complete the octet and chlorine accept it to complete its octet. Thus sodium form positive ion and chlorine form negative ion.
Similarly barium and calcium are present in group 2. Both have two valance electron. When they lose them cation are formed.
Other option are incorrect because,
Option B have sulfur and oxygen which are anion.
Option C have chlorine which is also anion
Option D have chlorine, sulfur and oxygen that are anions.
<span>Let x = amt of distilled water
:
A simple equation
.25(16) = .10(x+16)
4 = .10x + 1.6
4 - 1.6 = .1x
2.4 = .1x
x = 2.4/0.1
x = 24 oz of distilled water
:
:
Prove this by seeing the amt of antiseptic is the same (only the % changes)
.25(16) = .10(24+16)
4 = .1(40)
