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.

A. ---, 2, 2, ---
B. 2, ---, ---, 2
C. 2, ---, 2, ---
Answer:
2 NaF + Br2 --> 2NaBr + F2
Explanation:
Well first I notice that there are two flourines on the products side so we need to put a 2 of NaF. Now there are 2 sodiums on the products side so we have to put another two in front of NaBr.
2 NaF + Br2 --> 2NaBr + F2

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
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.

¿Cuántos moles de bióxido de Nitrógeno (NO 2) se forman cuando reaccionan 5 moles de Nitrógeno (N 2)?
Answer:
10 moles de NO2
Explanation:
Tenemos la ecuación de la reacción como sigue;
N2 (g) + 2 O2 (g) → 2 NO2 (g)
Asi que;
Si 1 mol de nitrógeno produce 2 moles de NO2
5 moles de nitrógeno producirán 5 * 2/1 = 10
Por tanto, se producen 10 moles de NO2 moles

A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?
Answer:
V₂ = 236.84 mL
Explanation:
The relation between pressure and volume is inverse.
We can write it as follows :
[tex]P_1V_1=P_2V_2[/tex]
We have,
P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.
So,
[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]
So, the new volume of the gas is 236.84 mL.

Answer:
belajar jangan malas malasJay 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?
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
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 Titanioselect three of the following compounds that are ionic
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.

Answer:
C. A one (1) is assumed when there is no coefficient
Explanation:
The following chemical equation is given in the attachment:
2H2 + O2 → 2H2O
In this reaction, Hydrogen (H2) and oxygen (O2) gases are the reactants and they combine to form H2O, which is the product. It is necessary that, in accordance to the law of conservation of matter, the same number of atoms of each elements on the reactant side equates that on the product side. When this happens, the equation is said to be BALANCED.
However, to balance an equation, COEFFICIENTS are used. In this equation above, coefficients 2 is used in front of both H2 and H2O but no coefficient is used in front of O2. This is because 1 mole of oxygen is on the reactant and product side respectively. However, one is assumed when no coefficient is written i.e. O2 means 1 mole of oxygen molecule.

Which best represents a physical change?
A. formation of a new substance
B. formation of a precipitate
C. condensation
D. bubbling
Answer:
The answer I would go with is A formation of a new substance.
Explanation:
This is because physical change includes changes of state. Some could be changing from a liquid to gas or solid to gas. B is not even an answer that should be considered because it doesn't fit into the category. C and D represents some of the examples of the process of physical change. Like boiling, bubbling, melting, or freezing. So the best would be A.
What special label do you have to use when naming ionic compounds with transition metals?
A) Roman Numerals
B) Greek Numerals
Naming Ionic compounds with transition metals requires the use of a roman numeral. The charge of the metal ion must be written in the name of the compound with a roman numeral. This is because transition metals can have more than one valence (or charge).
