I should think that Yolanda should use litmus paper throughout the reaction as its color will tell when the mixture is neutral and therefore then, when she can stop adding either the hydrochloric acid or the sodium hydroxide or if one or the other needs to be added to make the solution approach neutral. Blue litmus paper stays blue in a neutral solution, but will turn red in an acidic solution.

Which part of the earth do the suns direct rays hit during the summer solstice
sergey [27]
The sun is at the solstices on roughly June 21 and December 21.

June 21 is the "Summer" solstice in the Northern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Cancer, about 23.5° North of the equator.

December 21 is the "Summer" solstice in the Southern hemisphere.
At that time, the sun is directly overhead at a point on the Tropic
of Capricorn, about 23.5° South of the equator.

The headlights of a typical truck are powered by a 12 V battery. What current do they draw if the resistance is 4.8 ohms?
vodomira [7]
Solve this using Olm's law, which relates current (C), voltage (V), and resistance (R). Olm's law says:
I \: (current ) ={\frac {V \: (voltage) }{R\:(resistance)}}

We are told that voltage, V = 12V, and resistance, R = 4.8 <span>Ω. Plug these values into the equation and solve for current:
</span>I = \frac{V}{R}\\&#10;I = \frac{12}{4.8}\\&#10;I = 2.5A&#10;&#10;
<span>-----
Answer: Current = 2.5 Amperes</span>

4. Some early mornings , dew drops can be found on grass or a car parked outside,
horsena [70]

In some early mornings , dew drops can be found on grass or a car parked outside, but not on other materials such as the sidewalk because  the night -time temperature on grass and the car went below the dew point, but  the temperature of the concrete did not drop enough to reach the dew point  level

Dew can be formed on any object when the temperature of the object drop. When this happen, the object will be cool which will eventually cool the surrounding air around the object.

Dew drops is as a result of condensation in the air. When the cool air causes the air vapor to convert to liquid. The dew will form when the temperature of the object balances with the dew point in the surrounding environment.

In some early mornings , dew drops can be found on grass or a car parked outside, but not on other materials such as the sidewalk because  the night -time temperature on grass and the car went below the dew point, but  the temperature of the concrete did not drop enough to reach the dew point  level

Therefore the correct option is therefore A
