Answer:
With a short life cycle, greenhouse gas fixation ability, and high lipid production capacity, we use cyanobacteria as an efficient biofuel platform. Carbon dioxide released by the burning of fossil fuel and industrial emissions can be captured and used by these organisms efficiently.
Explanation:
What do cyanobacteria use for energy production?
oxygenic photosynthesis
They commonly obtain their energy through oxygenic photosynthesis, which produces the oxygen gas in the atmosphere of Earth. The name cyanobacteria comes from their color (Greek: κυανός, romanized: kyanós, lit.
Intermolecular forces do not have any effect on determining the physical properties of
substances such as surface tension and melting point.
True or false
Answer:
False
Explanation:
The physical properties of melting point, boiling point, vapor pressure, evaporation, viscosity, surface tension, and solubility are related to the strength of attractive forces between molecules. These attractive forces are called Intermolecular Forces.

Answer:
Alpha > beta>gamma
Explanation:
Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.
Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.
Answer:
[tex]\boxed {\boxed {\sf Gamma, beta, alpha}}[/tex]
Explanation:
Alpha. beta, and gamma particles are all emitted from an unstable or radioactive nucleus during radioactive decay.
Alpha particles are essentially helium ions, made of 2 protons and 2 neutrons. It has an atomic mass of 4 atomic mass units.Beta particles are also known as electrons. They have masses of 1/1840 atomic mass units.Gamma particles are actually just rays or photons of electronegative energy emitted. They have no mass or a mass of 0 atomic mass units.So, if we place the mass in increasing order (least to greatest), then it is gamma (0 amu), beta (1/1840 amu) and alpha (4 amu).

2. How many moles are in 34.0g of Silver hydroxide?
Answer:
0.272 mol AgOH
Explanation:
Figure out the amount of AgOH in mass, and to find the amount of moles–you just divide the given amount (34g) by the molar mass of AgOH (125g) to figure out the amount of moles. 34/125 = 0.272 mol AgOH.

A whale is swimming in the ocean. It communicates with another whale by sending out a sound. Which of the following best
describes how the sound gets to the other whale?
A.
All of the sound absorbed by water changes to heat before getting to the other whale.
В.
The sound is transmitted through water until it reaches the other whale.
C.
All of the sound is diffused in
the water until only a faint sound reaches the other whale.
.D
The sound is reflected in the water before it gets to the other whale.
Answer:
A.
The sound is transmitted through water until it reaches the other whale.
Explanation:
When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.
The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.
How sound may transmit from one place to another?The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.
In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.
It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.
Therefore, the correct option for this question is A.

Many plants in rainforests have leaf tips that come to a point, so precipitation drains off the leaf. This helps to keep the plant safe from harmful germs. Based on this info, what resource is prevalent in a rainforest?
Answer:
rainfall/water
Explanation:
The possession of drip tips by the leaves of plants in the rainforest is a form of adaptation against high rainfall. Without the drip tips on leaves, water will persist on the surface of leaves, and in conjunction with the warm climate, promotes the growth of pathogens such as fungi and bacteria.
Hence, the possession of drip tips on leaves is an indication of the prevalence of water in the rainforest region.
The maximum allowable concentration of Pb2+ ions in water in a local community is 1.51 x 10-8 M. Could a chemist use 2.00 mL of 0.12 M KBr solution on a 5.00 mL sample of tap water to prove through a precipitation reaction that the water supply is safe? Show all work and reasoning
Answer:
The water supply is not safe.
Explanation:
Ionically, the reaction is;
Pb^2+(aq) + 2Br^-(aq) -------> PbBr2(s)
Amount of Br^- reacted = 2/1000 * 0.12 = 2.4 * 10^-4 moles
From the reaction equation;
1 mole of Pb^2+ requires 2 moles of Br^- for complete precipitation
x moles of Pb^2+ requires 2.4 * 10^-4 moles of Br^-
x = 1 * 2.4 * 10^-4 /2
x = 1.2 * 10^-4 moles of Pb^2+
Concentration of Pb^2+ precipitated from 5ml of tap water = 1.2 * 10^-4 * 1000/5
Concentration = 2.4 * 10^-2 M
The amount of Pb^2+ found in the water is greater than the maximum allowable concentration of Pb2+ ions in water in a local community which is 1.51 x 10-8 M. Therefore, the water supply is not safe.

It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.
These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.

What are the only elements that make up organic compounds?
Question 2 options:
A)
Carbon, hydrogen, oxygen, and nitrogen
B)
Germanium, hydrogen, potassium, and nitrogen
C)
Carbon, hydrogen, lithium, and silicon
D)
Silicon, hydrogen, carbon, and nitrogen
The only elements that make up organic compounds are in option A. Carbon, hydrogen, oxygen, and nitrogen.
Organic compounds are compounds that primarily consist of carbon and hydrogen atoms. However, organic compounds can also contain other elements such as oxygen and nitrogen, which are commonly found in biological molecules. Carbon forms the backbone of organic compounds, providing the structural framework, while hydrogen is frequently bonded to carbon. Oxygen and nitrogen are also essential elements in organic compounds, participating in various functional groups and forming bonds with carbon and hydrogen.
Therefore, option A (Carbon, hydrogen, oxygen, and nitrogen) is the correct choice as it includes the elements that are predominantly found in organic compounds.

How do you know if a compound is covalent
Answer:
Compounds containing two elements (binary compounds) can either have ionic or covalent bonding. If a compound is made from a metal and a non-metal, its bonding will be ionic. If a compound is made from two non-metals, its bonding will be covalent.
