Answer:
pretty sure its Scientific laws are statements about observed experimental facts, while theories are explanations of natural phenomena.
Answer:
Explanation:
The objective here is to draw the Lewis structure for the polyatomic trisulfide anion and to be sure all resonance structures that satisfy the octet rule are included.
The Lewis structure for Polyatomic trisulfide anion
The first step is to the layout the skeleton of the Polyatomic trisulfide anion
S S S
However, the next step is to make sure we fill in the bonding pairs of electrons on the central atom.
Then , we move over to filling the lone pairs electrons before we finally have the Lewis structure for Polyatomic trisulfide anion as shown in the image below.
.ANSWER:Copper is a ductile metal
EXPLAIN :This means that it can easily be shaped into pipes and drawn into wires. Copper pipes are lightweight because they can have thin walls. They don't corrode and they can be bent to fit around corners.
Answer : Option 3) Tin and Silver.
Explanation : The elements which will be malleable (thin sheets) and good conductors of electricity has to be a metal.
i) Iodine and Silver - Iodine is a non-metal and is crystalline in nature so, it cannot be malleable. Although silver is a malleable element and is a good conductor of electricity, but the combination cannot be right. Also iodine is bad conductor of electricity.
ii) Iodine and xenon - Iodine is non malleable and bad conductor of electricity, whereas xenon is a noble gas which cannot be malleable but is a good conductor of electricity.
iii) Tin and Silver- Both are metals in nature and possess the property of being malleable and good conductors of electricity.
iv) Tin and xenon - Tin is although malleable and good conductor of electricity xenon is a gas which is good conductor of electricity but cannot be malleable.
Answer:
NaNO₃
KNO₃
Ca(NO₃)₂
Explanation:
The possible cations for the salt. = Na⁺ , K⁺ , Ca²⁺
The anion for which the formula has to written = NO₃⁻
The salt is of white color.
The possible salts may be:
<u>NaNO₃ </u>
<u>KNO₃</u>
<u>Ca(NO₃)₂</u>
Missy Mae can have one of these salts.
The color of NaNO₃ is from transparent to white.
The color of KNO₃ is white.
The color of NaNO₃ is from white to light grey.
