Explanation:
It is known that for 
, ppm present in 1 
are as follows.
1 
= 0.494 ppm
So, 150 
= 
= 0.15
Therefore, calculate the equivalent concentration in ppm as follows.
= 0.074 ppm
Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
Answer:
The conservation of energy principle states that energy can neither be destroyed nor created. Instead, energy just transforms from one form into another. So what exactly is energy transformation? Well, as you might guess, energy transformation is defined as the process of changing energy from one form to another. There are so many different kinds of energy that can transform from one form to another. There is energy from chemical reactions called chemical energy, energy from thermal processes called heat energy, and energy from charged particles called electrical energy. The processes of fission, which is splitting atoms, and fusion, which is combining atoms, give us another type of energy called nuclear energy. And finally, the energy of motion, kinetic energy, and the energy associated with position, potential energy, are collectively called mechanical energy. That sounds like quite a lot, doesn't it? Well it is, but don't worry, it's actually all pretty easy to remember. Next, we'll explore all of these kinds of possible transformations in more detail. Different Types of Energy Transformations Chemical energy is the energy stored within a substance through the bonds of chemical compounds. The energy stored in these chemical bonds can be released and transformed during any type of chemical reaction. Think of when you're hungry. When you eat a piece of bread to satisfy this hunger, your body breaks down the chemical bonds of the bread and uses it to supply energy to your body. In this process, the chemical energy is transformed into mechanical energy, which you use to move, and which we'll cover in more detail in a moment. It also transforms it into thermal energy, which is created through the metabolic processes in your body to generate heat. Most of the time, chemical energy is released in the form of heat, and this transformation from chemical energy to heat, or thermal energy, is called an exothermic reaction. Next, there are two main types of mechanical energy: kinetic energy and potential energy. Kinetic energy is the energy associated with the motion of an object. Therefore, any object that moves has kinetic energy. Likewise, there are two types of potential energy: gravitational potential energy and elastic potential energy. Gravitational potential energy is associated with the energy stored by an object because of its location above the ground. Elastic potential energy is the energy stored by any object that can stretch or compress. Potential energy can be converted to kinetic energy and vice versa. For example, when you do a death-defying bungee jump off of a bridge, you are executing a variety of energy transformations. First, as you prepare to jump, you have gravitational potential energy - the bungee cord is slack so there is no elastic potential energy. Once you jump, you convert this gravitational potential energy into kinetic energy as you fall down. At the same time, the bungee cord begins to stretch out. As the cord stretches, it begins to store elastic potential energy. You stop at the very bottom when the cord is fully stretched out, so at this point, you have elastic potential energy. The cord then whips you back up, thereby converting the stored elastic potential energy into kinetic energy and gravitational potential energy. The process then repeats

here u go :P
Answer:
D.- Using a sterile liquid and eliminating exposure to microorganisms.
Explanation:
Remember that Redi´s experiment is going to be with different jars cover the top. In this case, if the liquid is sterile that means any living thing is present there. so if by passing the time, there are no microorganisms, this is going to be the results that the spontaneous generation does not exist. From a non living liquid there can not produce a living thing.
The Big Bang theory is one of the ones used most frequently nowadays to describe how the cosmos came into being.
<h3>What does big bang theory state?</h3>
According to this theory, the universe formed 13.8 billion years ago as a result of the primordial atom, a single particle, exploding and generating an unprecedented cosmic disaster. The universe is always expanding, according to the same theory.
The key supporting data for the big bang theory are:
The galaxies to getting further and distant from us. This distance is taken at high speeds. In other words, the distance between galaxies is inversely correlated with their spacing velocity. Our perception of galaxy dysthanization occurs because the universe is continually expanding, according to this data, which is known as the "Hubble Law," and this hypothesis also explains that The cosmos has already been unified.
According to the big bang theory, the cosmos was extremely hot at the time of its creation; if this is accurate, we should find some proof of this warmth. Radio astronomers discovered this proof when they noticed that microwaves with a temperature of 2,725 degrees Kelvin included cosmic background radiation. This radiation is perhaps proof of the universe's high temperature.
Last but not least, the Big Bang most likely contributed to the abundance of hydrogen and helium elements.
