Answer: Your answer was pretty close, but we could make it better! Simply put, ohm's law states that by doubling the voltage across a circuit, the current will also double. You could also say that it was a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit, or (E = IR). Hope this helps!

Do you think MgO has a higher or lower
melting point than NaCl? Why?
Answer:
Magnesium Oxide (MgO) has a higher melting point than Sodium Chloride (NaCl) which is around 2,800 degrees Celcius. This is because its Mg2+ and O2- ions have a greater number of charges, and so form stronger ionic bonds, than the Na+ and Cl– ions in Sodium Chloride.

The size of the gray circle represents atomic radius, or
the size of an atom. Which area of the periodic table
has elements with the largest atomic radius?
Answer: Here u go
Explanation:
Atomic radii varies in a predictable way across the periodic table. The atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

1Which statement about plant cells is true? A A plant cell cannot contain both a nucleus and chlorophyll. Incorrect answer B A plant cell can contain both chlorophyll and a nucleus. Incorrect answer C A plant cell must contain chlorophyll, but can have no nucleus. Incorrect answer D A plant cell has neither a nucleus nor chlorophyll.
Answer:
B A plant cell can contain both chlorophyll and a nucleus.
Explanation:
All plants are eukaryotic organisms i.e the cells of all plants possess a membrane-bound nucleus that houses their genetic material (DNA). In addition to this, most plant cells also contain a unique organelle called CHLOROPLAST, which they use to capture the energy from sunlight in order to perform a process called PHOTOSYNTHESIS.
According to this question, plant cells can contain both chlorophyll and a nucleus. They can possess chlorophyll because chlorophyll is a pigment in their chloroplast that captures the light energy.
Ciara’s bike has rusted, which means that the iron in the metal changed to rust.
What has occurred?
an energy formation
an exothermic reaction
a chemical reaction
a precipitate formation
Answer:
CChem Reaction
Explanation:
Cuz it big brain time
The iron in the metal changed to rust, which is a chemical reaction. Therefore, option (C) is correct.
What is the rusting of iron?The rusting of iron is an oxidation reaction in which the iron combines with oxygen in the air in the presence of water to produce Fe₂O₃.xH₂O, a hydrated iron (III) oxide.
This hydrated iron (Ill) oxide is rust and the color of rust is reddish-brown. This reddish-brown rust can be seen on iron nails, pipes, and railings. on. Rust is formed when the iron is exposed to oxygen in the presence of moisture and is not an instantaneous reaction. Rusting of iron takes place over a long period of time.
Fe (s) + O₂ (g) + xH₂O (l) → Fe₂O₃. xH₂O (s)
The oxidation state of iron increases which is followed by the loss of electrons as a result of the rusting reaction. Iron(III) oxide or ferric oxide has the iron atom has an oxidation state of +3.

What is the relationship between variable x and variable y?
As variable x increases, variable y increases.
As variable x increases, variable y decreases.
Both variables show a trend toward decreasing values.
No distinct relationship exists between variables x and y.
Answer:
So x is usually called the independent or explanatory variable, and y the dependent or response variable. Another way to think about it, sometimes, is that x is used to predict y. So x is something that comes before y in time. That is why, for example, height at age 2 is on the x axis and height at age 18 on the y
Explanation:

x is independant and y in dependant .

What is the mass of 1.2 mol IrI3?
Answer:
690 g IrI₃
Explanation:
To convert from moles to grams, you have to use the molar mass of the compound. The molar mass of IrI₃ is 572.92 g/mol. You use this as the unit converter in this equation:
[tex]1.2molIrI3 * \frac{572.92g}{1mol} = 687.504 g IrI3[/tex]
Round to the lowest number of significant figures which is 2 to get 690 g IrI₃.
A sample of gas has a volume of 10 ml at 2 atm. The pressure increases to 4 atm. What is the new volume?
Answer:
The answer is 5 mLExplanation:
In order to find the new volume we use the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{10 \times 2}{4} = \frac{20}{4} \\ [/tex]
We have the final answer as
5 mLHope this helps you

Answer:
The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures).

How many moles of NH3 can be produced from 3.76 moles of nitrogen
in the following reaction:
N2 (g) + 3 H2 (g) → 2 NH; (g)
The number of moles of NH₃ obtained from the reaction is 7.52 moles
The balanced equation is given below:
N₂ + 3H₂ —> 2NH₃From the balanced equation above,
1 mole of N₂ reacted to produce 2 moles of NH₃.
Finally, we shall the number of mole of NH₃ produced by the reaction of 3.76 moles of N₂. This can be obtained as follow:
From the balanced equation above,
1 mole of N₂ reacted to produce 2 moles of NH₃.
Therefore,
3.76 moles of N₂ will react to produce = 3.76 × 2 = 7.52 moles of NH₃.
