Mixtures

Explanation:

The forms of matter that exists without having chemical bonds between them are mixtures.

Mixtures are impure substances. They are made of matter that are not chemically bonded to one another.

Here are some of the characteristics of a mixture:

  • Composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass
  • The constituents retain their identities i.e physical properties are not altered.
  • The constituents reacts differently to changed conditions.
  • They can easily be separated into constituents by physical methods.

Many natural mixtures exists and several others can be formulated. Examples include air, sea-water, muddy water, alloys e.t.c

what is the balanced equation for the reaction of solid magnesium metal with oxygen gas to produce solid magnesium oxide
GaryK [48]

Answer:

2Mg + O₂ ⟶ 2MgO

Explanation:

Step 1. Start with the most complicated-looking formula (O₂?).

Put a 1 in front of it.

Mg + 1O₂ ⟶ MgO

Step 2. Balance O.

We have fixed 2 O on the left. We need 2O on the right. Put a 2 in front of MgO.

Mg + 1O₂ ⟶ 2MgO

Step 3. Balance Mg.

We have fixed 2 Mg on the right-hand side. We need 2 Mg atoms on the left. Put a 2 in front of Mg.

2Mg + 1O₂ ⟶ 2MgO

Every formula now has a coefficient. The equation should be balanced. Let’s check.

<u>Atom</u>  <u>On the left</u>  <u>On the righ</u>t

  Mg             2                  2

  O                2                  2

All atoms are balanced.

The balanced equation is

2Mg + O₂ ⟶ 2MgO

1.1 Define the concept risky behaviour?​
ICE Princess25 [194]

Answer:

Risky behavior or risk-taking behavior is defined according to Trimpop (1994) as “any consciously, or non-consciously controlled behavior with a perceived uncertainty about its outcome, and/or about its possible benefits, or costs for the physical, economic or psycho-social well-being of oneself or others.” In addition to this broad definition, there are other definitions of risky behavior depending on the field of research. While in the economic view, risk is defined in terms of the variability of possible monetary outcomes, in the clinical literature, the risk is generally defined as exposure to possible loss or harm (Schonberg, Fox, & Poldrack, 2011). Turner et al. (2004) described risk-taking behavior further as either a socially unacceptable volitional behavior with a potentially negative outcome in which precautions are not taken, such as speeding, drinking and driving, drugs abuse, unprotected sex and so on.

Which of the following nuclei would be the most stable?
ValentinkaMS [17]
Ten protons would be Neon, but the most stable? I'd have to say 12 neutrons in contrast to the 10 protons.  Not too negative in balance.

My teacher has asked me to research the amount of energy released through combustion on a natural gas stove and to show how the
Masteriza [31]

Answer:

I wouldn't be entirely sure, but I believe your teacher means the energy as in being transferred such as when you are cooking something and how it varies.  Avocado oil has a higher content of unsaturated fats. Olive oil contains a high ratio of monounsaturated fatty acids to satured fatty acids. Avocado oil has a very high smoke point, between 480°F and 520°F (270°C). The oil is a good choice for stir-fry recipes and other high-temperature cooking. It is ideal for searing meats and frying in a wok.

Olive oil’s smoke point varies depending on the processing and the grade. Light olive oil has a smoke point of 430°F, making it suitable for medium-heat frying.

Extra virgin olive oil has a low smoke point, around 220°F. It is unsuitable for high-temperature cooking or frying.

You should keep in mind that when you heat oil to its smoking point, it loses its nutrient content and becomes dangerous for consumption. It leads to the formation of toxic compounds and harmful free radicals which are carcinogenic.

Explanation:

All oils are different.  The "smoke point" of the oil is how the oil is classified.  The smoke point is the temperature at which the oil begins to smoke.  It begins to burn at this point and it can be a fire hazard.  The "flash point" is the temperature at which the oil ignites.

How can you identify balanced forces
solmaris [256]

Answer:

To determine if the forces acting upon an object are balanced or unbalanced, an analysis must first be conducted to determine what forces are acting upon the object and in what direction. If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced.
