Answer:
d. ii.
Explanation:
Hello!
In this case, according to the displayed decimal placed by each balance, we can notice that:
i. Displays 1 decimal place.
ii. Displays 2 decimal places.
iii. Displays 4 decimal places.
iv. Displays 3 decimal places.
Thus, since the measured-out masses have two decimal places each, we infer that the used balance was d. ii as it displays two decimal places.
Best regards!
The options for given question are as follow,
1) Methane molecules show hydrogen bonding.
<span>2) Ammonia molecules show hydrogen bonding. </span>
<span>3) Methane has stronger hydrogen bonding than ammonia. </span>
<span>4) Both the compounds do not show hydrogen bonding. </span>
<span>5) Both the compounds have strong hydrogen bonding.
</span>
Answer:
Correct answer is Option-2 (Ammonia molecules show hydrogen bonding).
Explanation:
Hydrogen bond interactions are formed when a partial positive hydrogen atom attached to most electronegative atom of one molecule interacts with the partial negative most electronegative element of another molecule. So, in Ammonia hydrogen gets partial positive charge as nitrogen is highly electronegative. While the C-H bond in Methane is non-polar and fails to form hydrogen bond interactions.
Answer:
847 mL
Explanation:
Step 1: Find conversion
1 L = 1000 mL
Step 2: Use Dimensional Analysis
<em>We see that Liters and Liters cancel out, so we simply multiply.</em>
847 mL
Answer:
Temperature, mass, and the type of material are factors that affect the thermal energy of an object.
Material with the higher specific heat will have more thermal energy than material with lower specific heat if they both have the same mass and temperature.
The answer is Aphelion since that is the point in a planet, comet or asteroids orbit around a sun when it is furthest
