Jay painted the inner four walls of a box. Then he put an ice block into it such that it did not touch the walls, but he couldn't do the same when he put water in that box. Why?
Answers
Answer:
Liquid takes the shape of container, so it will always touch the walls of the box in which you put it.
Explanation:
We know that a solid has a definite shape and a definite volume hence it occupies only its own volume in the box, it does not touch the walls of the box.
However, a liquid does not have a definite shape and volume. It occupies the volume of the box. Therefore, the liquid water must definitely touch the walls of the box.

Determine el número de moles presentes en una esfera de titaniode 0.5 cm de radio, sabiendo que la densidad del titanio es de 4507kg/m³. =433
Answers
Answer:
0.0493 moles de Titanio
Explanation:
Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:
Volumen de la esfera:
Volumen esfera = 4/3π * Radio³
Volumen = 0.5236cm³
En m³ (1m³ = 1x10⁶cm³):
0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³
Masa en gramos:
5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio
Moles -Masa molar Ti: 47.867g/mol-:
2.36g de Titanio * (1mol / 47.867g) =
0.0493 moles de TitanioX

The reason of why rainforest plants adapted to be a different shape as compared to the desert plants is because of option d. as the rainforest environment is different than the desert environment.
Adaption of the rainforest plants to the different shapes and size?
It can be like:
Drip tips - where plants contains leaves with pointy tips.Buttress roots - These contain large roots that have ridges that develop a large surface area. Epiphytes - It lives on the branches of trees high up in the canopy.hence, The reason of why rainforest plants adapted to be a different shape as compared to the desert plants is because of option d. as the rainforest environment is different than the desert environment.

Explanation:
To think that we are the reason for global warming and everything would make the next person a little insulted but when you think about it a long time ago when there was not many technological advancements there was not complains of global warming or anything until recently. Temperatures are starting to rise and more and more pollution is filling our atmosphere. As it could be true that it might not be entirely our fault as humans I think we took a major part in it.

select three of the following compounds that are ionic
Answers
Explanation:
Ionic compounds are compounds formed by the bonding of a metal with a non metal.
A. NO2
This is not an ionic compound because N and O are non metals.
B. CaCl2
This is an ionic compound because Ca is a metal and Cl is a non metal.
C. KI
This is an ionic compound because K is a metal and I is a non metal.
D. CO2
This is not an ionic compound because C and O are non metals.
E. H2O
This is not an ionic compound because H and O are non metals.
F. NaCl
This is an ionic compound because Na is a metal and Cl is a non metal.
It would be helpful if you could explain the process or do a few to show me how to do it. You don't need to do it all just one would help.

Group 1 has charges of 1+
Group 2 has 2+
Group 3 has 3+
Group 4 has +/-4
Group 5 has -3
Group 6 has -2
Group 7 has -1
Group 8 doesn’t form ions because they don’t react.
Do you notice a pattern? Group 4 is like the middle and both sides.
For example, lets look at the first question:
Na (Sodium) is in group 1. This means that its ions have a 1+ charge. And Cl (Chlorine) in in group 7, meaning it has a 1- charge.
2) In the next step we try to cancel out the charges by finding the lowest common multiple. But, in this case, there is no need because 1+ and 1- cancel out to have an overall charge of 0 when they are in a compound.
3) Lastly, we put the two elements together. If we multiplied it to cancel the charges in the previous step, then we need to put the number we multiplied it by in front of it.
Lets do another example:
Magnesium is in group 2, therefore it forms a 2+ ion.
Oxygen is in group 6, therefore it forms a 2- ion.
Both charges cancel out and we are left with MgO.
The next example involved the 2nd step.
Lithium is in group 1, so it forms 1+ ions.
Oxygen is in group 6, so it forms 2- ions.
In order to cancel out the charges, we have to multiply lithium by to to get Li2 with a 2+ charge.
Now the charges cancel and we can put them together to get Li2O.
Hope this helped! If you have any more questions please ask :))

If an object has a Mass of 11g and a volume fo 13mil, what is its density?
A.143g/ml
B.0.85g/ml
C.2g/ml D.24g/ml
Answers
Answer:
[tex]\boxed {\boxed {\sf B. \ d \approx 0.85 \ g/mL}}[/tex]
Explanation:
Density is found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the object is 11 grams and the volume is 13 milliliters.
[tex]m= 11 \ g \\v= 13 \ mL[/tex]
Substitute the values into the formula.
[tex]d= \frac{11 \ g}{13 \ mL}[/tex]
Divide.
[tex]d=0.846153846 \ g/mL[/tex]
Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.
[tex]d \approx 0.85 \ g/mL[/tex]
The density is about 0.85 grams per milliliter.

6 grams of sodium chloride (NaCl) is dissolved to create 0.5 L of solution. What is the
molarity of this solution?
Answers
Answer:
0.206M
Explanation:
Molarity, which refers to the molar concentration of a substance can be calculated using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
According to the provided information, mass = 6grams, volume = 0.5L
Since molar mass of NaCl = 23 + 35.5
= 58.5g/lol
Mole = mass/molar mass
Mole = 6/58.5
Mole = 0.103mol
Hence;
Molarity = 0.103/0.5
Molarity = 0.206M
