True or False: Plants don't have brains, but they still adapt to their environments.
Answer:
True
Explanation:
I just took that last year, and got a100%
True, Plants don't have brains, but they still adapt to their environments.
What is adaptation?Adaptation is a process where they are changing their nature to suit the environment.
We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.
Hence, plants have no brains, but they still adapt.

What happens to the dry ice after sometime?
Answer:
As a rough rule, five pounds of dry ice will turn from a solid to a gas in 24 hours. It's best to pick up the block of ice just a few hours before your party so it's as frozen as possible when the bash starts.

Explain how Earth is heated through radiation
Answer:
Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.
Explain What is an elementary reaction and how is it related to a reaction mechanism
Answer:
The sequence of individual steps, or elementary reactions, by which reactants are converted into products during the course of a reaction is called the reaction mechanism. The overall rate of a reaction is determined by the rate of the slowest step, called the rate-determining step.

Could cellular respiration
happen without photosynthesis? Explain your
reasoning
Answer:
No
Explanation:
Without photosynthesis, there would be no sugar, without which there could be no cellular respiration.Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP.

Determine the mass of 2.86 mole Co(NH3)6Cl3
Answer:
765 g Co(NH₃)₆Cl₃
General Formulas and Concepts:
Reading the Periodic Table of ElementsExplanation:
Step 1: Define
2.86 mol Co(NH₃)₆Cl₃
Step 2: Define conversions
Molar Mass of Co - 58.93 g/mol
Molar Mass of N - 14.01 g/mol
Molar Mass of H - 1.01 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of Co(NH₃)₆Cl₃ - 58.93 + 6(14.01) + 18(1.01) + 3(35.45) = 267.52 g/mol
Step 3: Dimensional Analysis
[tex]2.86 \ mol \ Co(NH_3)_6Cl_3(\frac{267.52 \ g \ Co(NH_3)_6Cl_3}{1 \ mol \ Co(NH_3)_6Cl_3} )[/tex] = 765.107 g Co(NH₃)₆Cl₃
mol Co(NH₃)₆Cl₃ and mol Co(NH₃)₆Cl₃ cancel outWe are left with grams (mass)Step 4: Simplify
We are given 3 sig figs. Follow sig fig rules.
765.107 g Co(NH₃)₆Cl₃ ≈ 765 g Co(NH₃)₆Cl₃

Explanation:
The reaction for the combustion of acetylene is shown. Explain why this reaction is a redox reaction by identifying the oxidation numbers that change, what is oxidized, what is reduced, and what happens to the electrons during the reaction. 2C2H2 + 5O2 → 4CO2 + 2H2O
Answer:
2 C2H2 (g) + 5 O2 (g) → 4 CO2 (g) + 2 H2O (l)
Explanation:
Redox reaction: In this type of reaction, oxidation and reduction reaction occurs simultaneously in same chemical reaction.
2C_2H_2+5O_2\rightarrow 4CO_2 + 2H_2O2C
2
H

+5O

→4CO

This reaction is a redox reaction :
Removal of hydrogen or addition of oxygen is termed as oxidation. in above reaction, removal hydrogen from acetylene gives carbon-dioxide.
Removal of oxygen or addition of hydrogen is termed as reduction. in above reaction, removal of one oxygen atom from oxygen molecule with addition of two hydrogen atoms gives water
The oxidation number of carbon in acetylene is -2.
The oxidation number of carbon in carbon-dioxide= +4
Oxidation number of carbon increases after the reaction which means that carbon is getting oxidized.
The oxidation number of oxygen in oxygen gas = 0
The oxidation number of oxygen in water = -2
Oxidation number of oxygen decreases after the reaction which means that oxygen is getting reduced.
The electrons released during oxidation are transferred to the species which are undergoing reduction reaction.
Answer:
Just put this, or something like it:
The oxidation number of carbon changes from -1 to +4.
The oxidation number of oxygen changes from 0 to -2.
Carbon is oxidized.
Oxygen is reduced.
Electrons are transferred from carbon to oxygen.

Explanation:
True or False Gases do have a definite shape and volume.
Answer:
false
Explanation:
Answer:
False
Explanation:
It is false as the particles of gases keep moving. They have very weak molecular bonds. They are so weak that they can move freely anywhere and in any direction. Even if you trap some gases and a closed bottle, they keep moving. We can't measure what the shape is or what the volume is. Therefore, it is false.

what happens to the electronegatity when you go from top to bottom on the periodic table?
Answer:
It decreases
Explanation:
As you go down a group from top to bottom, the electronegativity decreases. Across a period, electronegativity increases from left to right.
Electronegativity is the tendency with which the atoms of the element attracts valence electrons in a chemical bond. The more electronegative an element is, the stronger its affinity for electrons. Electronegativity values less than 2 shows an element is a metal. Metals are generally electropositive.This is a science question. What is the skateboarder’s acceleration?

If you wanted to change the polarity of hydrogen bromide (HBr) by substituting the bromine by a different atom. Which atom would increase the polarity of the molecule?
Answer:
Chlorine
Explanation:
The Polarity of an atom is characterized as the dipole to dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule. Thus, the 'chlorine' atom would help in enhancing the polarity of hydrogen bromide(HBr) with 3.16 electronegativity as we know, the electronegativity increases if we move upwards in the periodic table.
