Answer:
D.
Explanation:
I had looked it up on the quiz site
It is tasteless and colorless.
Answer a:
<span>A 1.5 V battery, the electromagnet picked up an average of 6 paper clips, while with the 6.0 V battery, an average of 23 paper clips were picked up. Battery of 6.0V is 6.0/1.5 = 4 times stronger than battery of 1.5 V
Answer b:
</span><span>Ratio of the number of paper clips picked up using the 6.0 V battery to the number picked up using the 1.5 V battery is = 23/6 = 3.8 </span>≈ 4.
Answer c:
As the voltage power increase, more paper clips were picked up by electromagnet. This indicated that there is a direct relationship. Mathematically it can be expressed as:
Voltage Power α Number of paper clips that were picked up
The atomic mass on the periodic table represents the sum of number of protons and number of neutrons.
Atomic mass = Number of protons + number of neutrons
Hope this helps!
Answer:
negative, positive, increase
Explanation:
From the given question,
During the formation of bond, between two atoms with difference between their electronegativity-
- The more electronegative atom, will pull the electrons towards itself , and hence acquires a partial negative charge,
And,
- The less electronegative atom, will acquire a partial positive charge.
- The more the difference between the electronegativity of the atoms, the more would be the magnitude of partial charge.
- And, the less would be the difference between the electronegativity of the atoms, the lesser would be the magnitude of partial charge.
